3 Fix rpn2cql: structure, relation problem for serverChoice YAZ-849
4 Problem was that for things mapped to cql.serverChoice the relation
5 would sometimes be omitted when it should not. Eg for relation "all".
9 Document zoom extraArgs YAZ-817
11 Fix ZOOM: crash extended services diagnostics YAZ-846
12 The immediate fix is to prevent ZOOM_set_dset_error from removing
13 current task from connection. This, however, has been assumed in a
14 number of places so this fix is rather large unfortunately.
18 Make yaz_log_reopen async-signal YAZ-845
19 Fixes potential dead-lock issue with YAZ_DAEMON_LOG_REOPEN flags for
24 CCL: new feature s=spl (split-list) that splits terms in a search into
25 sub-phrases of all sizes (from 1 up to the number of terms) with order
26 preserved. For 3 terms the CCL search
29 @or @or @or @and @and a b c @and "a b" c @and a "b c" "a b c"
31 Solr: don't set defType=lucene in URLs if extraArgs already defines it.
35 Add lock/unlock for YAZ log writes YAZ-843
39 Fix incorrect parsing of URLs @:9999/somebase&url=http://some.host YAZ-842
43 yaz-client: deal with excess bytes HTTPS case YAZ-833
45 ZOOM C: deal with excess bytes HTTPS case YAZ-833
47 Allow Windows installer for PATH to be updated YAZ-841
49 Add Ubuntu Vivid 15.04 to list of Deb's to built
53 Allow Content-Type application/sru+xml YAZ-840
55 New yaz_xml_get_prop utility YAZ-839
57 Fix zebrasrv [warn] ir_session (exception) YAZ-838
59 Document itemorder-setname and list all ILL options
63 Extend get_org_info (snippets) to return original string YAZ-836
64 Two new functions have appeared: icu_chain_get_org_info2 and
65 icu_iter_get_org_info2 with a 4th parameter being a pointer
66 to the original string.
68 Fix tcpip.c compilation failure on VC9 YAZ-835
70 Fix icu_iter_get_norm returns invalid size for some input YAZ-834
71 The icu_iter_get_org_info returns information based on string
72 as it appears on tokenize step.
76 Deal with excess bytes in HTTP response for keepalive YAZ-830
78 Refactor ssl_put and tcpip_put to one function YAZ-832
80 Refactor ssl_get and tcpip_get to one function YAZ-831
82 Fix SEGV yaz-client for HTTP decoding error YAZ-829
84 Fix buffer overflow in cmd_elements in yaz-client YAZ-828
88 Fix test_sru.sh fails in pazpar2 YAZ-826
89 Unfortunately a regression occurred with YAZ 5.10.0 that would make
90 Pazpar2 fail for HTTP connections.
94 Use CONNECT for SSL backends and for Z39.50 thru HTTP proxy YAZ-825
95 Introduce cs_create_host2 which returns if connection should be
96 proxy aware (HTTP:absoluteUri or Z39.50 proxy:vhost in init).. For CONNECT,
97 the connection is NOT proxy aware (no absoluteUri and no Z39.50 vhost).
99 Fix http proxy fails with yaz-client YAZ-824
103 Fix 0 ptr reference for OPAC records from XML YAZ-822
107 Extend yaz daemon facility to assist int log rotation YAZ-818 YAZ-819
111 record conv: 'select' return org record if no x-path match YAZ-814
113 retrieval: pick matched element-set rule YAZ-813
115 Fix crash in record conv rule 'select' YAZ-812
119 record_conv: selection by X-Path YAZ-811
120 That's a new step in record conversion system (<select path=".."/>)
122 Document record render parameters for ZOOM - including base64
126 Fix application/x-www-form-urlencoded + empty YAZ-810
127 A SEGV occurred if Content-Type was "application/x-www-form-urlencoded"
128 and empty content was supplied.
130 Fix yaz-iconv man page for typos and incorrect example. YAZ-809
132 Fail hard if Bison is not found and is needed YAZ-808
136 Enable YAZ backtrace for programs YAZ-802
138 Update NMAKE makefile to use Visual Studio 2013 along with ICU 54.1,
139 Libxml2 2.9.2, Libxslt 1.1.28.
141 Fix daemon: parent process stops before child YAZ-806
142 Try to fix the situation where parent process stops before
143 child has acknowledged it .. SIGUSR2 back!
145 daemon: log message when keepalive stops.
149 Fix yaz-marcdump segfault YAZ-801. Problem in YAZ 5.6.0/5.7.0 and
150 would make yaz-marcdump crash when from-character set was issued.
154 Dump backtrace in case of SIGABRT, SIGSEGV YAZ-787
155 New function yaz_enable_panic_backtrace which enables backtrace
156 handler for current process. The handler will call backtrace always,
157 then gdb to provide as much detail as possible.
161 When marc-8 charset is specified when decoding MARC records, yaz-marcdump
162 and ZOOM record render will inspect leader 9 and switch to UTF-8
163 (Unicode) if that holds 'a'. This changes behavior, but is considered
164 safe because only MARC21 with leader 9='a' are Unicode. YAZ-800
166 Fix cs_put may reconnect if send fails. YAZ-798
170 Fix cannot build YAZ on jessie : libgnutls-dev is gone YAZ-797
174 Extended comstack with outgoing IP YAZ-795.
175 For cs_create_host + cs_create_host_proxy the vhost may be followed
176 by a outgoing host/IP. Separator is blank.
180 Add YAZ_EXPORT to cql_transform_r fixes YAZ-793 . This issue fixes
181 linker error with yazpp on Windows.
185 Fix uri array may overflow in yaz_solr_encode_request YAZ-775
187 Fix PQF to Solr conversion may produce invalid Solr query YAZ-792
189 0 ptr reference in handling Solr response with error YAZ-791
191 Fix annoying warning about wrbuf_putc on newer GCC YAZ-789
193 Fix documentation about --installa option YAZ-788
197 daemon: properly report when receiving SIGUSR2 from child YAZ-785
201 xmalloc: throw assert for clearly invalid calls to malloc and
202 improve diagnostics YAZ-783 YAZ-784
206 Stop building debs for Ubuntu raring, quantal, oneiric.
208 CCL YAZ-781: for multiple use attributes in a specification the
209 generated RPN will perform @or on each term.
210 For spec: term u=31 u=1016
211 the CCL: t will generate: @or @attr 1=31 t @attr 1=1016 t
213 log YAZ-780: avoid mixed log files by perform only one write(2) per log entry.
215 CCL YAZ-779: combo qualifier should allow for forward references
217 Fix buildconf.sh, automake too old on centos5 YAZ-778
218 Achieved by adding AM_PROG_CC_C_O and requiring AM 1.9 instead.
219 The AM_PROG_CC_C_O is obsolete for newer AM, but 1.14 (Debian jessie)
220 accepts it without a warning.
224 GFS: client_query_charset conversion YAZ-777
225 This is a feature for Z39.50 clients that sends queries that are not
226 UTF-8 encoded. WIth client_query_charset, GFS will convert from the
227 encoding given to UTF-8.
229 Echoed SRU arguments support YAZ-776
230 This is achieved with new function yaz_srw_get_pdu_e.
232 ZOOM: expire times set for redis/memcached YAZ-772
233 For both redis and memcached option --expire=seconds sets expire
234 time for a result-set/search. Default time is 600 seconds (10 minutes).
238 No [rest of output is omitted] limit for yaz_log YAZ-774
240 Optimize icu_iter_get_org_info. Reduce calls to u_strToUTF8.
242 For ICU testing, pass -o to yaz-icu. This will test the
243 icu_iter_get_org_info function.
245 Fix null ptr reference for freeReplyObject YAZ-773
249 Allow ZOOM caching using redis. New ZOOM option "redis" controls it.
251 RPM: do not build with libmemcached support. The libmemcached library
252 on CentOS 5/6 does not work reliably for us (redis to the rescue).
254 configure: only allow libmemcached version 0.40 or later. That's the version
255 on Debian squeeze. We recommend libmemcached version 1.0 or later. If
256 that's not an option, consider redis.
260 Fix dup ZOOM_EVENT_RECV_RECORD events for SRU/Solr YAZ-768
262 Fix zoom+memcached: present request out of range YAZ-767
266 CCL: add new qualifier r=omiteq which will omit relation=equals
267 for ordered relations. This should be used in combination with either
270 GFS: prevent truncation/overflow in retrieval phase. YAZ-763
272 Solr: simplify yaz_solr_decode_response
274 Solr: use different local var for string manipulation
276 Solr: Get rid of hardcoded limit of extra_args
278 Solr: encode lucene query type YAZ-736
279 Make sure the queries are treated as traditional "lucene", because that's
282 Fix ZOOM HTTP redirect failing on Windows+Solaris YAZ-755
286 Build packages for Ubuntu Trusty Tahr 14.04 LTS
288 wrbuf_cstr: fix off by one error.
290 wrbuf_buf: make it always return non-NULL
291 Also, wrbuf_buf will return same buffer as previous call to wrbuf_cstr.
295 Doc: move main YAZ manual to book.xml; use nxml YAZ-758
297 zoomsh: offer option -a apdulog
298 As we're used to from yaz-client and GFS based servers.
300 ZOOM: new setting apdufile. Sets name of APDU file. If not given,
301 existing setting apdulog takes effect.
303 Add odr_setprint_noclose. It's like odr_setprint, but does not fclose at
308 Add re-entrant CQL/Solr/RPN query conversion functions.
309 The re-entrant functions are: cql_transform_r,
310 cql_transform_rpn2cql_stream_r, solr_transform_rpn2solr_stream_r.
311 These have same functionality as cql_transform,
312 cql_transform_rpn2cql_stream, solr_transform_rpn2solr_stream. They
313 return the additional infomration as WRBUF to make them re-entrant.
315 Remove CQL to Solr conversion and base solr_transform_t on
316 cql_transform_t. The RPN to Solr is indeed in use. It uses exact same
317 data structure as cql_transform_t.
319 cql2pqf utility allows RPN to Solr conversion
321 Fix assert in ZOOM when http connect fails YAZ-757
323 --- 5.0.22 2014/04/09
325 ZOOM: Call cs_rcvconnect during HTTP redirect YAZ-754
327 wrbuf_cstr: make it thread safe YAZ-753
329 yaz_log_init_file may take fd=<no> to open log file at the FD given.
331 --- 5.0.21 2014/03/21
333 Offer new utility function zget_AttributeList_use_string.
335 New conversion step, solrmarc, for record conversion module.
337 --- 5.0.20 2014/03/13
339 Fix gcrypt initialization for threaded mode. On systems were GnuTLS
340 did not initialize gcrypt for threaded mode, wrbuf_sha1_write could
343 --- 5.0.19 2014/03/10
345 Fix ZOOM_connection_Z3950_search: Assertion YAZ-750
346 The standalone ZOOM sort was completely broken since 5.0.13.
348 ZOOM: generate event Connect rather than None for partial connect
349 (in fact getaddrinfo resolving).
351 ZOOM: only supply clientIP for InitRequest. Rather than for all
354 GFS: peer_name adds X-Forwarded/Client-IP to value YAZ-749
356 COMSTACK flag CS_FLAGS_DNS_NO_BLOCK. This will enable non-blocking
357 getaddrinfo . This flag is passed to cs_create macro and cs_create_host,
358 cs_create_host_proxy functions. ZOOM C uses this flag. YAZ-744
360 New "Facets" section in the documentation.
362 --- 5.0.18 2014/02/27
364 Call exsltRegisterAll in yaz_init_globals, so that all applications
365 using YAZ will have EXSLT things enabled.
367 Use extraArgs in key for memcached ZOOM C caching YAZ-747.
369 Update various URLs to the re-organized SRU pages at LoC.
371 --- 5.0.17 2014/02/26
373 Fix ZOOM_connection_connect SEGVs if host==NULL YAZ-746. Problem
374 introduced in 5.0.12.
376 Fix: Setting env YAZ_LOG makes YAZ hang YAZ-745
377 yaz_init_gloabsl calls yaz_log_init_globals calls yaz_log_mask_str_x .
378 Do not call yaz_init_globals from log_mask_str_x. Problem introduce
381 --- 5.0.16 2014/02/25
383 tcpip/SSL COMSTACK: connect tries all getaddrinfo addresses YAZ-743
385 --- 5.0.15 2014/02/24
387 Fix gcrypt not properly initialized YAZ-740.
389 --- 5.0.14 2014/02/19
391 Describe memcached option for ZOOM.
393 ZOOM: throw present request out of range again YAZ-739
394 Was removed in YAZ 5.0.13.
396 --- 5.0.13 2014/02/18
398 yaz_log MUTEX protected and pthread_atfork is used to avoid dead-lock
399 with localtime_r when threads + fork is used (such as Metaproxy).
401 yaz-config: quote some RHS values (that might include blanks)
403 zoomsh: shows SearchResult-1
405 zoomsh: sortby command
407 zoomsh: use proper list of connections and result sets YAZ-725
409 Avoid yaz_log in sigterm handler for GFS YAZ-737
410 Logging is still performed, but outside sig handler.
412 New ZOOM C feature: result-set caching with memcached. Example:
413 zoomsh "set memcached --server=memcachehost" "connect zurl" "search query"
415 Remove SSL via OpenSSL support YAZ-732
416 Also deprecate two functions from comstack that aren't working with
417 GnuTLS: cs_get_ssl, cs_set_ssl_ctx.
419 Revert "Bison: use %name-prefix directive rather than -p option"
421 --- 5.0.12 2014/01/22
423 Prefix URL with http:// if sru setting hints SRU/Solr mode YAZ-731
425 SRU GET/Solr base URLs may hold additional ?args YAZ-729
426 ZOOM option extraArgs already does this, though. It seems useful
427 when dealing with Solr targets to limit by filter, eg.
428 http://lui.indexdata.com:8080/solr4/select?fq=database:3902
430 Remove #fragment for HTTP request encoding YAZ-730
432 Doc: Update list of DLLs/LIBs
434 Doc: update href link to Unix utils and Git.
436 --- 5.0.11 2014/01/15
438 ZOOM: fix "lost connection" problem with servers that uses both squid
439 and another proxy behind it that returns Location headers with relative
442 zoomsh: do not use readline for stdin (no tty) YAZ-724
443 Just use fgets in that case. If the user hits Ctrl-D a new-line
446 zoomsh: empty command ignored YAZ-723
447 rather than performing exit of zoomsh.
449 yaz-url utility offers option -v to enable verbose mode.
451 yaz_url uses yaz_check_location and offers verbose mode.
453 Add new function yaz_check_location.
454 This function gets an absolute URI from Location (HTTP redirect).
456 cookie API: introduce yaz_cookies_reset
458 Update cql.y for newer bison YAZ-720
459 The important part is that YYLEX_PARAM and YYPARSE_PARAM are no
460 longer supported. Instead one must use %lex-param and %parse-param .
462 --- 5.0.10 2014/01/09
464 ZOOM/yaz-client: Cookie handling; deal with relative URI in Location
467 rpn2solr: support truncation left(2), left&right(3) YAZ-718
469 Mention SRU version 2.0 in yaz-client man page.
473 ZOOM/yaz-client: allow SRU searchRetrieveResponse with incorrect
478 Make cs_parse_host public.A
480 Fix double HTTP dump (-a log would show HTTP packages twice). Bug
481 introduced in YAZ 5.0.6.
485 Fix buffer corruption for yaz-ztest record fetch.
489 Allow yaz-ztest to return user-defined records (one record per file).
490 This is enabled by defining environment variable YAZ_ZTEST_XML_FETCH.
492 Prevent early truncatin of HTTP log. (ODR_PRINT for HTTP streams).
493 Use the stream write instead of odr_printf which has a 4K tmp buffer.
495 Fix encoding of 0x00a4 (unicode to danmarc) YAZ-713
499 Add support for MARC-in-JSON. yaz-marcdump and the record conversion module
500 can read and write this format. For record format JSON, yaz-ztest returns
501 MARC-in-JSON records.
503 iconv: fixes and more tests for danmarc character set encoding. 0xa733 is
504 converted to @Ã¥ , 0xa732 is converted to @Ã… instead of @a733, @a732 .
508 Improve error reporting for ICU chains YAZ-707
509 Report config element+rule when ICU status is "failure".
511 ZOOM: stop fetching if present response has no records YAZ-710
512 Some targets return less records than their hit count would suggest.
513 This prevents ZOOM from continuing to fetch records if any present
514 response has 0 records in the response.
516 Ensure that GFS calls exit if any listener fails YAZ-710
517 Before, if XML config was in use, it would start the default
522 yaz-ztest: -V shows version (like yaz-client -V)
524 New iconv encoding: danmarc YAZ-692
526 yaz-client: lslb, ssub, mspn are Odr_ints now YAZ-705
528 daemon: only wait for immediate child rather than all children. YAZ-704
530 yaz-client: fix setting of SRU record schema. If scheme was unset, it
531 could lead to invalid memory reference.
535 yaz-ztest returns schema for MARCXML test records. SRU require that
536 recordSchema for records.
538 GFS: make surrogate diagnostic when yaz_record_conv_record fails -
539 instead of non-surrogate diagnostic. This is a per-record failure.
541 GFS: Allow multiple listenrefs YAZ-554. A server in yazgfs configuration
542 may refer to multiple listeners now. Attribute listenref is a comma separated
545 GFS: Use xmlconfig path as prefix for fnames YAZ-702. When -f
546 option is given for GFS, the dirname of filename (for -f) is used
547 as prefix for options such as cql2rpn, ccl2rpn, etc.
549 Content-Type charset fixes YAZ-701 . Do not inspect charset in
550 Content-Type header for SOAP when decoding SRU. The payload (XML)
551 itself tells what encoding it is. In response, never supply encoding
552 in Content-Type. The response payload (XML) tells what it is (with no
553 encoding in XML it's UTF-8).
555 HTTP decoding: allow blanks in URL paths YAZ-700
559 Various fixes for how SRU 2.0 is encoded. Fix NS for SRU 2.0 diagnostics
560 and facets. Ensure recordData and recordSchema are always present in
561 record element, because they are required.
563 Remove deprecated functions yaz_uri_val .. and yaz_uri_val_int. Never used
566 Simplify in a lot of places using odr_strdupn.
568 odr_create_Odr_oct: null terminate the buffer. Some applications rely on it.
572 Increase various buffers in GFS's statserv_options_block
573 Change many 'unsigned char *' to 'char *' for ODR-related utilties.
574 This change makes many type-casts redundant, and, thus simplifies code.
576 Remove last bits of WAIS support.
578 Remove member 'size' from Odr_oct.
580 Slim down the public part of 'struct odr'. Most elements are not part
581 of struct Odr_private.
583 Add support for SRU 2.0. Since SRU 2.0 is incompatible with earlier
584 versions of SRU, yaz-client and zoom C are using SRU 1.2 by default.
585 In particular facets are supported in both client - and server side.
586 Facets are also supported for Z39.50 and is carried in additionalSearchInfo
587 of searchRequest/searchResponse with OID 1.2.840.10003.10.1000.81.5 AKA
588 "Facet-1" in oid.csv. The info is defined in facet.asn (which covers
589 both request/response). This is what a search handler in the GFS
590 will see (regardless of whether operating in SRU mode or Z39.50).
592 Changes to the srw.h (SRU/Solr) definitions include:
593 - New element in Z_SRW_searchRetrieveRequest, queryType (char*) and query
594 (char*), which replace union query and query_type (int). This is because
595 SRU 2.0 supports a queryType parameter. This also means that, to carry
596 PQF, in SRU we can now use queryType=pqf and query=PQFstring , rather than
597 x-pquery=PQFstring (extention parameter). The extension parameter
599 - New element, packing, that has information about SRU
600 2.0 recordPacking (not to be confused with SRU 2.0 recordXMLEscaping).
602 New element in Z_SRW_searchRetrieveResponse, resultCountPrecision.
604 New element, packing, in Z_SRW_explainRequest.
606 New elements in Z_SRW_scanRequest, queryType and scanClause.
607 These replace query_type and scanClase untion. This is similar to what
610 --- 4.2.69 2013/10/01
612 GFS: log when closing down - at least SIGTERM YAZ-684
613 Also change formatting WRT PID logging a bit.
615 Improve display of MARC records with multi-byte subfield IDs YAZ-695
616 In some rare cases subfield identifiers are multi-byte characters.
617 This will try to deterime length of those and split accordingly.
618 This affects display in line mode as MARCXML/MarcXchange. The encoding
619 of ISO2709 is the same.
621 Change inp argument to const for yaz_read_UTF8_char.
623 yaz-marcdump: fix leaks for MARCXML parsing. YAZ-694
625 MARCXML parsing: avoid skipping 1st field if no leader. YAZ-693
627 Better check of marc leader info YAZ-691
628 Problem is that some systems generate MARCXML/MarcXchange with
629 funny headers. These will not work if encoded as ISO2709.
630 Some tests produce new output, due to updated warning messages
632 cql2pqf: allow PQF queries from stdin (because CQL is also allowed)
634 yaz-client: display MAB records YAZ-689.
635 Thanks for Heiko Jansen for this patch.
637 New utility z_get_HTTP_Response_server which allows both HTTP server name
638 and HTTP server URL to be given in response.
640 Debian: do not depend on obs tcl8.3.
642 Debian: do not depend on obs libicu36-dev.
644 --- 4.2.68 2013/09/23
646 GFS: pass additionalSearchInfo to search memeber search_input if
647 given. Otherwise pass otherInfo. Request for facets and other search
648 related things will be passed there in future versions of YAZ.
650 New ZOOM setting, authenticationMode, which allows authentication
651 paramters to be encoded in the URL rather than via HTTP Basic auth.
654 rpn2solr: fix nested AND/OR handling. YAZ-685
656 Add comparison routines for some Z-types, such as NamePlusRecord,
657 RPNQuery, Query, RecordComposition and OtherInformation.
659 --- 4.2.67 2013/09/19
661 Don't decode MAB as MARC. Just like we don't attempt to decode
662 HTML/XML as MARC. Fixes MAB display problem that was introduced in 4.2.64.
664 CCL: allow quoted terms for date ranges. YAZ-681
666 Introduce ccl_parser_qual_search. This function makes old function
667 ccl_qual_search, from YAZ 2, available again.
669 Add yaz_facet_list_to_wrbuf. YAZ-683
671 --- 4.2.66 2013/09/11
673 ZOOM: fix record handling for Solr. ZOOM_record_get would return 0, if
674 schema was given for search. YAZ-675
676 Add Solr date range searches. YAZ-621
678 --- 4.2.65 2013/08/22
680 ZOOM: another fix for record caching (introduced in YAZ 4.2.64).
682 --- 4.2.64 2013/08/21 (Broken WRT ZOOM C, do not use)
684 ISO2709/MARC parse most octet aligned records; not just those that
685 are known to be ISO2709/MARC. This makes ZOOM and yaz-client
686 MARC parse more records instead of just dumping as is. YAZ-670
688 ZOOM: proper caching for variations of record schema. YAZ-671
690 Solr: Check for enging / and perhaps commands (select/term) YAZ-651
692 --- 4.2.63 2013/07/17
696 --- 4.2.62 2013/07/11
698 New utility z_get_HTTP_Response_details - an extended version of
701 New utility yaz_url_get_error which returns error message of last
702 failed yaz_url_exec call.
704 yaz-url and url functions: allow max HTTP redirects to be controlled.
706 New functions yaz_file_glob2, yaz_xml_include_glob.
707 These functions takes a flags parameter, which, for now only controls
708 whether to fail inclusion of a non-existing file (without glob
709 pattern) - flags YAZ_FILE_GLOB_FAIL_NOTEXIST.
711 --- 4.2.61 2013/06/20
713 For MARC XML parsing, allow record without leader. A fake/default leader
714 is inserted and a warning is tagged with the record.
716 ICU: fix leak in in icu_iter_get_org_info.
718 --- 4.2.60 2013/06/14
720 ICU: fix bug in icu_iter_get_org_info (un-init variable).
722 --- 4.2.59 2013/06/11
724 Implement z_HTTP_header_remove.
726 --- 4.2.58 2013/06/11
728 ICU: Disallow 0 ptrs for some ICU string utilities.
730 ICU: new utilities icu_iter_get_org_info and icu_chain_get_org_info:
731 returns original tokens (before normalization).
733 CCL: avoid z39.58/regex truncation when not needed. Apply only the
734 conversion of those masks, when absolutely necessary.
736 CCL: configurable masking character - @mask. Default masking character
739 HTTP encoding: remove Transfer-Encoding header. YAZ uses content_len and
740 full response anyway, so a Transfer-Encoding header will obstruct the
743 --- 4.2.57 2013/05/15
745 COMSTACK: @ uses AF_UNSPEC . But we prefer AF_INET6 over others when
746 picking a socket. Problem is that some systems has IPV6 support, but
747 we can't create sockets for them, so we pick AF_UNSPEC first.
749 HTTP encode. Proper Content-Length YAZ-660. For yaz_encode_http_response
750 use content_len to determine resulting Content-Length in HTTP response
751 and NOT Content-Length supplied in headers by user.
753 z_HTTP_header_add_basic_auth uses z_HTTP_header_set rather than
754 z_HTTP_header_add, to avoid having two Authorization headers by mistake.
756 Fix problem with HTTP decoding. For HTTP 1XX, 204, 304 assume no
759 Fix yaz_base64decode to use proper signed. Problem occurred on platforms
760 with big endian and unsigned char (by default).
762 --- 4.2.56 2013/04/26
764 Fix yaz-client connect (crash in 4.2.55).
766 --- 4.2.55 2013/04/26
768 Fix proxy/host problem for ZOOM that could occur if unix sockets
771 New Debian package libyaz4-dbg.
773 Fix problem with cs_close hang/wait in SSL mode. Invoke gnutls_bye
774 differently in tcpip_close.
776 --- 4.2.54 2013/04/17
778 Windows installer of YAZ includes YAZ4J as a component.
780 CQL: allow "extra terms" again, by default. Thus, the CQL parser
781 accepts a superset the standard. This reverts to CQL as of YAZ 4.2.51
782 and earlier. CQL parser may operate in strict mode where queries
783 not conforming to the standard BNF are rejected (syntax error).
784 Whether the CQL parser operates in strict mode is controlled with
785 cql_parser_strict . Strict mode enabled with option -S for utilities
786 cql2pqf and cql2xcql .
788 yaz-ztest: returns OPACXML records for syntax=XML and element set=OP.
790 --- 4.2.53 2013/04/10
792 New charset, MARC-8c, which is like MARC-8 but allows control characters
793 0x01 through 0x1F, except ESC to be passed through verbatim.
795 Fix a problem with duplicate sub field character in MARC output. Problem
796 happened only when output was MARC-8 encoded.
798 --- 4.2.52 2013/04/03
800 yaz-ztest: Use hash for fake hit count. Before, random number was used.
801 This is problematic for unit tests using yaz-ztest. This patch also makes
802 a hash for CQL queries. For RPN, any term with a leading digit will be
803 treated as pseudu hit count (to force any particular hit count by a client).
805 yaz-ztest: return unique MARC dummy records. Beyond record offset
806 24, the author surname is patched with offset to make all records
809 COMSTACK: make @ bind to IPV6+IPV4 consistenly and avoid depending
810 on system wide default (/proc/sys/net/ipv6/bindv6only).
811 @4 binds to IPV4 only. @6 binds to IPV6 only.
813 Update CQL API documentation a bit
815 CQL: don't accept extra terms for queries. Makes the CQL parser
816 stricly conformant to the standard.
818 --- 4.2.51 2013/02/12
820 GFS: scan handler gets extra_args from request and may return extra
821 response data . That's for SRU only.
823 Solr scan support for ZOOM and yaz-client. Patch from Simon Jacob.
825 --- 4.2.50 2013/01/30
827 New function, yaz_xml_to_opac, to convert from OPACXML to Z39.50 OPAC.
829 OPACXML: sync spelling of availabilityDate in XML to that of Schema
830 opaxxml.xsd. The schema had the correct spelling of this member always.
831 The ASN.1 was mis-spelled and still is (API change) - we are
832 not changing this. However, the OPAC to XML conversion had yet
835 GFS: Allow conversion between Z39.50 OPAC and OPACXML via retrieval
838 New function, z_ext_record_oid_nmem, which is similar to
839 z_ext_record_oid but takes NMEM rather than ODR
841 --- 4.2.49 2013/01/18
843 ICU: New conversion element 'join' which joins tokens into one
844 with a custom character given by rule attribute.
846 --- 4.2.48 2013/01/10
848 New GFS search member: present_number. This is a hint to the
849 search handler how many records are going to be fetched immediately
850 following search. There's no guarantee that it's going to be the case,
851 since it depends on hit count (for Z39.50 piggyback) and whether errors
854 Make a few functions static (private). The functions getbyte_stream,
855 ungetbyte_stream and yaz_gets are now private. They were never declared
858 yaz-marcdump: exit(5) for serious decoding errors
860 ISO2709 decoding: be more picky WRT header
862 GFS: bail out of fetch if last_in_set is set. Until now, last_in_set,
863 was only used as to indicate that next-result-set-position should be
865 http://www.loc.gov/z3950/agency/markup/04.html#Next-result-set-position
866 Based on patch from Ashley Sanders.
868 Make some functions static/private in PQF parsing. Those functions were
869 never declared in a public header and so should not be in use by
870 applications based on YAZ.
872 --- 4.2.47 2012/11/23
874 ZOOM: special options to control APDU logging.
875 Using ZOOM_connection_option_set(c, "saveAPDU", "1") will enable
876 logging of APDUs until "saveAPDU" option is set again. If logging is
877 already enabled the effect is that current APDU buffer is cleared.
878 Using ZOOM_connection_option_set(c, "saveAPDU", "0") disables
879 logging (default behavior on new connection).
880 The APDUs sent/received can be obtained by using
881 Using ZOOM_connection_option_get(c, "APDU") or
882 ZOOM_connection_option_getl(c, "APDU", &l).
884 GFS: relay implementation_version from backend
885 From 3.0.40 and later, implementation_version from backend was
886 not used in init response at all.
888 --- 4.2.46 2012/11/15
890 Fix cs_rcvconnect for SSL comstack GNUTLS. Did not work in non-blocking
891 mode at all. Probably never did.
893 Make a new version of ztest.pem that, at least, is not expired.
895 --- 4.2.45 2012/11/13
897 Fix description of CCL directive 'case'.
899 More tight checking of form arguments (yaz_uri_to_array). Makes
900 YAZ better at rejecting big and/or bad POSTs.
902 SRU decoding does not report more than up to 10 invalid arguments.
904 rpn2cql: less quotes in generated terms. Semantics unchanged, but
905 it's prettier this way.
907 --- 4.2.44 2012/10/25
909 New utility yaz_decode_init_diag. Defined in proto.h.
911 Allow HTTP protocol on unix local socket. Also Z39.50 database may be
912 given for unix local socket.
913 The COMSTACK string for doing so is:
916 unix:/myfile:tcp:localhost:9999/mybase
917 unix:/myfile:localhost:9999/mybase
918 unix:/myfile:http://fakehost/mybase
920 debian: Use dpkg-buildflags in build process.
922 --- 4.2.43 2012/10/19
924 ZOOM C: don't trust recordPosition always. Some servers, such as IGI
925 global's SRU service uses a recordPosition scheme starting from zero.
926 First record's position should be one
927 according to the standard.
929 --- 4.2.42 2012/10/18
931 Allow more namespaces for SRU. This is to allow, for example, an
932 incorrect namespace returned from server
933 http://services.igi-global.com/sru .
935 Minor fixes for compilation on Windows.
937 --- 4.2.41 2012/10/11
939 daemon: log total number of bad signals from child on stop so that it
940 is more easy to spot problems with child worker processes.
942 retrieval: empty backend name attribute omits element set
943 from being used in retrieval.
945 --- 4.2.40 2012/10/04
947 Implement Solr sort strategy "solr", similar to sru11 sorting.
948 This will implement the correct parameters on Solr requst to do
951 --- 4.2.39 2012/09/28
953 Implement ccl_qual_fitem2. Like ccl_qual_fitem but with diagnostic
956 MARC: Extra/missing indicator handled for MARCXML.
957 The indicator length is given in header and is the same for the
958 whole record. If attributes ind1, ind2 are missing, then content
959 character defaults to blank. Extra indicator attributes (beyond)
960 indicator length are treated as an error.
962 Reformat: delete trailing whitespace
964 --- 4.2.38 2012/09/17
966 MARC: fix non-ASCII characters for leader. This is to ensure we can
967 generate XML in UTF-8.
969 CCL: new special attribute s=ag . Almost s=pw,al but preserves words
970 in one node with structure word.
972 --- 4.2.37 2012/09/04
974 yaz-json-parse: JSON output may be pretty printed by using option
977 Increase default value of max message for Z39.50 Init for GFS, ZOOM
978 and yaz-client. Old value was 1 MB. New value is 64 MB.
980 --- 4.2.36 2012/08/22
982 yaz-client: don't display bogus records from SRU servers. Some SRU servers
983 return more records than given by *maximumRecords*. Skipping those in
986 record_render: simplify buffer return handling and fix at least one bad
987 memory reference, that broke the test_embed_record sometimes.
989 Allow http://user:pass@host notation for yaz_url_exec.
991 zoomsh: allow shell command to be executed. Via the system(3) call.
993 yaz_poll: Allow num_fds == 0
995 yaz-client: fix bad encoding of "itemorder item". The itemorder
996 item <no> - command forgot to use length of encoded Item Request
997 package. Error present since YAZ 3.
999 yaz-ztest: fix bad usage of session handle. Bug was introduced when
1000 result sets were saved (271a9c83).
1002 SRU recordPacking: guess record packing in response rather than looking
1003 at the recordPacking element which, OF COURSE, changed semantics in SRU
1006 Decode SRU 2.0 responses. The official namespace for responses, according
1007 to http://docs.oasis-open.org/search-ws/searchRetrieve/v1.0/cs01/schemas/sruRes
1008 appears to be http://docs.oasis-open.org/ns/search-ws/sruResponse .
1009 nature.com's server, however, usee namespace
1010 http://docs.oasis-open.org/ns/search-ws/sru-2-0-response . For this reason
1011 we are now using a glob-expr to match up the namespace. ZOOM C and
1012 yaz-client updated. Perhaps SRU 1.2 uses same namespace, I don't know.
1013 I can not find a single real example showing the "real" namespace in
1014 the documentation from OASIS. The namespace for requests is different
1015 from responses, but this is not added to YAZ yet, when we don't encode
1018 --- 4.2.35 2012/06/26
1020 zoom/record_render: add support for Base64 decoding fo MARC records
1021 within XML element. For example: "xml; charset=marc-8; base64=/my/text()"
1022 which will decode base64 + ISO2709 marc-8 encoded material from text node
1025 --- 4.2.34 2012/06/07
1027 Add missing definitions ZOOM_resultset_get_facet_field_by_index
1028 and ZOOM_resultset_facets_names.
1030 zoom: fix bad free for ZOOM_connect - happened when ZOOM connection
1033 Change APDU dump printing to avoid long leading blanks. For levels 16
1034 or larger the level is shown and the indentation is truncated but
1035 recursed with modula 8. This makes it still reasonable easy to read
1036 - even for nested BER dumps.
1038 Fix bug completeBER_n WRT too nested BER. Function completeBER_n could
1039 return 0 (incomplete package) in case where the BER package was
1040 considered too nested (return value of -2).
1042 dumpber: lines of level 15 are not indented further. Two spaces per
1043 indentation; indentation 15 or more is indented to a fixed indentation
1044 and augmented with a level=<no> indication.
1046 zoomsh: increase max size of command+args
1048 GFS: No limit in RPN buf size in CQL to RPN conversion.
1050 --- 4.2.33 2012/05/09
1052 New function for daemon utility, yaz_daemon_stop .
1054 Makes yaz_srw_sortkeys_to_sort_spec public on Windows.
1056 --- 4.2.32 2012/04/25
1058 Add some Bib-1/SRU diagnostics + mappings. Bib-1: 1073 and
1059 Bib-1 1074: Proxy failure. SRU: 1074: Proxy failure
1061 --- 4.2.31 2012/04/23
1063 YAZ daemon utility relays SIGUSR1 to child process.
1065 ZOOM: handle trailing slash for Z39.50 urls. Previously localhost:9999/
1066 would result in en empty database list - which in turn would result in
1067 encoding failure for search.
1069 Fix reading beyond string in yaz_sort_spec.
1071 --- 4.2.30 2012/04/11
1073 Add two new SRU diagnostics:
1074 236: Access to specified database denied
1075 1015: Init/AC: Maximum number of simultaneous sessions for Userid
1077 Document the very useful ZOOM-C option "apdulog".
1079 CQL to RPN: term may be passed through verbatim. This is enabled with
1080 truncation.cql . The assumption being that the term is already CQL.
1082 --- 4.2.29 2012/03/20
1084 record_conv: leader spec may be given for marc element.
1085 The leader spec is given as attribute leaderspec for element marc.
1086 For example to convert a MARC21 record from MARC-8 to UTF-8:
1087 <marc inputformat="marc" outputformat="marc"
1088 inputcharset="marc-8" outputcharset="utf-8 "leaderspec="9='a'"/>
1090 record_conv: allow user-XSLT params. For example:
1091 <xslt stylesheet="MARC21slim2DC.xsl">
1092 <param name="myparameter" value="myvalue"/>
1093 <param name="otherparameter" value="othervalue"/>
1096 record_conv: fix error handling for missing marc charsets.
1098 CQL: fix extra terms in wrong order.
1100 --- 4.2.28 2012/03/06
1102 record_conv: modify new API for conversion types. The conversion types
1103 may be passed in new functions yaz_record_conv_configure_t and
1104 yaz_retrieval_configure_t. Removing yaz_record_conv_add_type .
1106 Avoid mixed statement/variable declare; fixes compilation with Visual
1109 --- 4.2.27 2012/02/28
1111 Add non-standard SRU diagnostic: 235: "Database does not exist".
1112 Couldn't live without it. HTTP 404: "Not found" is just so anonymous.
1113 Update SRU to Bib-1 diagnostic maps accordingly.
1115 CCL: add two new diagnostics for unsupported masking. The new
1116 diagnostics are: "Embedded truncation not supported" and
1117 "Single charcacter mask not supported".
1119 --- 4.2.26 2012/02/23
1121 CCL: fix use of "term" field in sub queries. Bug introduced in YAZ 4.2.25.
1123 --- 4.2.25 2012/01/11
1125 Build YAZ for Ubuntu Oneiric.
1127 CCL: allow parantheses for proximity operands. For example CCL query
1128 (a) % (b) is now allowed.
1130 GFS: fix bend_assoc_is_alive. When cs_get returns 0 the association is
1131 marked dead, rather then being destroyed. If not, the session memory is
1132 being free'd before the search/scan handler is finished. Also destroy
1133 'request' memory in request_release rather than in various places,
1134 which resulted in leaks from time to time.
1136 --- 4.2.24 2011/12/21
1138 cql_sortby_to_sortkeys: honor sort prefix.
1140 RPN to CQL: always quote resulting terms. For bizarre reasons, JSTOR's
1141 SRU server returns 0 hits on ISSN searches unless a CQL term is quoted.
1142 The rpn2cql family of functions now always returns quoted CQL terms.
1144 Fix CQL to CCL conversion for multiple terms. Add two test cases as well.
1146 --- 4.2.23 2011/12/15
1148 Allow =val to be omitted for yaz_uri_to_array. Also, multiple &'s in
1149 sequence is treated as one. For example, &&a=b&&&c& is identical to
1152 --- 4.2.22 2011/12/05
1154 Add ZOOM_connection_save_apdu_wrbuf. This function may be used to save
1155 APDUs for a connection to a WRBUF.
1157 --- 4.2.21 2011/11/23
1159 Fix cql_sortby_to_sortkeys. Completely broken before.
1161 Make CCL's @truncation work again.
1163 --- 4.2.20 2011/11/09
1165 New ZOOM connection setting: tproxy. It's like proxy, but does not
1166 set Z39.50 proxy OID or change HTTP for proxy behavior. Can be used
1167 to set resolved address + port for a connection outside ZOOM itself.
1169 Fix atoi_n_check digit test. Thanks to Giannis Kosmas for spotting it.
1171 --- 4.2.19 2011/11/07
1173 Fix uninitialized variable in Solr spell support (could cause SEGV
1174 for SRU response decoding).
1176 Error handling for Z_APDU_close uses ZOOM_set_dset_error() to pass
1177 back-end's addinfo through into the ZOOM response addinfo.
1179 When ZOOM_set_dset_error() is passed an addinfo2 as well as addinfo,
1180 they are separated by a colon and a space rather than simply
1183 --- 4.2.18 2011/10/28
1185 Add support for Solr spell-checking/suggestions through ZOOM.
1186 If a Solr target has been configured correctly for spelling-checking
1187 and suggestions, these will now be returned on the ResultSet option
1188 "suggestions". zoomsh has been extended to show this with the cmd suggestions.
1190 --- 4.2.17 2011/09/28
1192 Fix function nmem_strsplit_escape2 which extends nmem_strsplit_escape
1193 with a flag whether to substitute escape sequences or not.
1195 --- 4.2.16 2011/09/22
1197 Fix nmem_strsplit_escape to substitute escape char properly.
1199 New option for zoomsh -e , which makes it abort on first error and
1200 return process exit code to indicate success/failure.
1202 YAZ options utility supports special option -- which makes all it treat
1203 all following arguments as non-options.
1205 --- 4.2.15 2011/09/16
1207 Fix yaz_file_path_resolve/yaz_path_fopen/yaz_fopen so that path is not
1208 searched if absolute filename is given.
1210 Fix conv_xslt() error-reporting when stylesheet is not found.
1211 (The value of fullpath is meaningless in this situation.)
1213 --- 4.2.14 2011/09/07
1215 Fix problem in CQL sort node creation: un-initialized memory.
1217 New ZOOM utility ZOOM_query_sortby2. That takes a strategy parameter: one of
1218 "z3950", "type7", "cql", "sru11" or "embed". The "embed" chooses type-7 or
1219 CQL sortby depending on whether Type-1 or CQL is actually sent to the
1222 New sortspec utilities: yaz_srw_sortkeys_to_sort_spec,
1223 yaz_sort_spec_to_srw_sortkeys, yaz_sort_spec_to_type and 7yaz_sort_spec_to_cql.
1225 rpn2solr supports Z39.58 truncation (104). Thus, CCL truncation mode t=z
1226 will make it possible to use both single-character mask (#) and wildcard (?)
1227 in CCL . Throw diagnostic for left truncation because that is not supported
1230 --- 4.2.13 2011/09/01
1232 Fixes for cql2rpn, cql2ccl and ccl2rpn; mostly in the area of special
1233 cases using escapes (\-sequences) and masking.
1235 PQF parse fix: A trailing backslash followed by end-of-string (\0)
1236 would result in a read one byte beyond string.
1238 rpn2ccl may use Z39.50 masking for terms (t=z).
1240 ICU check fix. Don't include library -lCrun on Solaris, unless present.
1242 ICU check fix: Use --cppflags-searchpath to determine ICU include files;
1243 not --cppflags (which seeems like an error in icu-config).
1245 --- 4.2.12 2011/08/27 RPM package only
1247 cql2ccl: fix conversion of terms: operator characters were not
1250 --- 4.2.11 2011/08/25 RPM package only
1252 ccl2rpn: Conversion to regexp-1 terms (trunc=102). For mode t=x, the
1253 CCL parser will map both # and ? to their regular expression
1254 quivalents (. and .*).
1256 rpn2cql: deal with truncation=102 (regexp-1). And ensure proper quoting
1257 of reserved CQL characters.
1259 cql2ccl: deal with both * and ? in conversion. Also leave escaped ones as
1260 is, so that they are passed through.
1262 --- 4.2.10 2011/08/24
1264 ZOOM SRU mode: more aggressive re-connect.
1266 Private function prox_unit_name() renamed to yaz_prox_unit_name() and
1267 made available as a utility function, declared in <yaz/logrpn.h>
1269 rpn2cql_structure() supports proximity nodes (except that the Type-1
1270 proximity node's "exclusion" binary is ignored, as there is no way to
1271 express that in CQL). Fixes bug #4564.
1273 --- 4.2.9 2011/08/18
1275 Fix SEGV that could occur if set command of zoomsh was given without
1276 value (2nd argument).
1278 Fix SEGV that could occur if unsupported transport was given for
1279 COMSTACK - say https (when SSL was unavailable).
1281 Build yaz-url on Windows too.
1283 --- 4.2.8 2011/08/11
1285 New utility to get web content. Header is url.h. A command line tool
1286 yaz-url is part of the distribution and packages.
1288 Fixes for SSL COMSTACK (when gnutls is in use).
1290 New functions yaz_base64{encode,decode}. Header is base64.h.
1292 --- 4.2.7 2011/08/03
1294 ZOOM C includes HTTP response buffer as additional info if it fails
1295 to decode the SRU response.
1297 Make wrbuf_json_puts available.
1299 --- 4.2.6 2011/07/28
1301 zoom: throw diagnostic for invalid value for option "sru". Before a
1302 bad SRU request was sent.
1304 Adding new utility wrbuf_vp_puts.
1306 Add cclxmlconfig.obj to win/makefile. It was missing completely.
1308 --- 4.2.5 2011/07/21
1310 ZOOM HTTP: use absoluteURI's in proxy mode as required by RFC 2616 (HTTP).
1311 Fix a bug in handling of cookies. Fix a bug that would occur if proxy +
1312 redirect was used at the same time.
1314 MARC line mode decoding: be less picky about length given - first
1315 5 digits of header that is.
1317 CQL to CCL conversion: deal with CQL proximity (cql_to_ccl function).
1319 Changes to decoding of SRU records: a record with recordPacking=xml is
1320 modified with a new root element <yaz_record> if the recordData contains
1321 multiple children elements. This is to make the record XML parseable
1324 RPN to Solr conversion: encode special characters.
1326 Generic Frontend Server: fix uinitialized member, stepSize.
1328 --- 4.2.4 2011/06/21
1330 Fix a bug in SRU decoding of records.. The database records stored
1331 had un-initialized memory, but it would only be seen with yaz_record_render
1332 and type_spec="ext" .
1334 Fix a bug in ccl_qual_dup introduced in 4.2.3.
1336 --- 4.2.3 2011/06/17
1338 Add new CCL utility, ccl_qual_dup, which makes a copy of a CCL bibset.
1340 --- 4.2.2 2011/06/10
1342 Add new utilities to convert from CQL to CCL . These utilities have
1343 prefix cql_to_ccl defined in cql.h.
1345 Defensive coding for an off-by-one bug in ucol_getSortKey. This could
1346 lead to memory heap corruptions when ICU utilities were in use.
1348 --- 4.2.1 2011/06/07
1350 Make compilation work without Libxml2.
1352 yaz-client: remove redundant blanks in display of searchResult-1 term
1355 --- 4.2.0 2011/05/18
1357 CQL: parse CQL sortby spec. The resulting sort spec is stored in the
1358 resulting CQL node (tree) in a new node CQL_NODE_SORT.
1360 CQL and GFS: add utility cql_sortby_to_sortkeys which converts CQL sortby
1361 1.2 node tree to CQL 1.1 spec. This in turn allows the generic frontend
1362 server to only consider srw_sortkeys and support both SRU 1.1 and 1.2.
1363 Note that the CQL sortby spec is only converted when the GFS is already
1364 converting from CQL to RPN (cql2rpn element).
1366 New function nmem_strsplitx. This is like nmem_strsplit but allows us to
1367 specify whether to collapse delimitors or not. The existing nmem_strsplit
1368 do collapse (collapse parameter = 1).
1370 Windows installer: For NSIS, set InstallDir depending on x86/x64.
1372 Rename internal func yaz_use_attribute_create. While non-static, this
1373 function is not declared in a public header.
1375 --- 4.1.7 2011/03/15
1377 Add -lCrun when linking with ICU on Solaris.
1379 More quicks character set conversions for OPAC records.
1381 --- 4.1.6 2011/03/10
1383 fix problem with record_render: records were converted (character set
1384 wise) even if no charset was given. Problem introduced in YAZ 4.1.5.
1386 --- 4.1.5 2011/03/08
1388 SRU: add methods for handling DADS SRU-proxy facets.
1390 Separate OPAC record character set for ZOOM_record. yaz_record_render
1391 allows a character set given as charset=from/opacfrom,to where 'from' is
1392 the character set of a bibliographic record, 'opacfrom' is character set
1393 of OPAC record and 'to' is the target character set.
1395 --- 4.1.4 2011/02/21
1397 yaz-client: show may XML format records. Command show followed by 'format'
1398 will format XML records retrieved using Libxml2's xmlDocDumpFormatMemory
1401 src/stemmer.c: Avoid using unnamed union. It is not supported by some
1404 For PHPYAZ: set YAZVERSION, not YAZ_VERSION.
1406 --- 4.1.3 2011/01/27
1407 Update yaz.spec to operate on both SLES11 / Centos 5.5.
1409 RPM: Release includes 'indexdata' name. Use indexdata in release name so
1410 this package can be distinguished from other vendors.
1412 yaz-config: Use exec_prefix, libdir, includedir . Use these variables
1413 as determined by configure
1415 yaz-config: set YAZ_VERSION env. php_yaz relies on it.
1417 GFS: Z_PresentStatus_partial_4 for missing record. If bend_fetch handler
1418 returns no error and no record, the present request is considered
1419 partial (only a subset of the records could be returned by backend), and
1420 so it is appropriate to set Present Status to partial-4.
1422 --- 4.1.2 2010/11/02
1424 Move yaz-config man pages to section 1.
1426 More documentation about Solr.
1428 tcp comstack: change behavior for @-specs (anyaddr). @ listens on
1429 AF_INET (IPV4) peers, and @6 listens to AF_INET6 (ipv6) peers.
1430 Previously @ listened on AF_INET6 which accepted both IPV4 and IPV6
1431 peers on some Linux systems. However, in general that does not work
1432 so YAZ can not rely on that to work. Debian changed behavior in this
1433 respect from Debian lenny to Debian squeeze (still testing as of Oct
1435 http://www.mail-archive.com/debian-devel@lists.debian.org/msg277726.html
1437 zoomsh: remove "debugging" output. Was added by mistake in 4.1.0.
1439 --- 4.1.1 2010/10/05
1441 Fix yaz-config output: echo_source not set correctly by configure.
1443 --- 4.1.0 2010/10/05
1445 Solr Web Service support for yaz-client and ZOOM.
1447 Define record syntax JSON. OID: 1.2.840.10003.5.1000.81.3 .
1449 --- 4.0.12 2010/08/17
1451 Z39.50 facet support. Facet specifications are passed for search in
1452 other-information with ASN.1 as defined in facet.asn and OID
1453 .10.1000.81.5 . Facets are expressed as an Attribute list as known
1454 from Type-1/RPN queries. Type 1 is field. Type 2 is sort order. Type
1455 3 is limit (number of entries to get in response). yaz-ztest returns
1456 dummy facets if a client asks for them.
1458 --- 4.0.11 2010/07/09
1460 CCL fixes: bug 2895 and bug 3539.
1462 GR1-display: add comma in display - was removed by mistake in
1465 Windows installer: bundle MSVCP90.dll - used by icuuc42.dll.
1467 SRU: Merge cookies on HTTP redirects (Giannis Kosmas <kosmas@lib.uoc.gr>).
1469 --- 4.0.10 2010/06/18
1471 ZOOM C: Add ZOOM_resultset_release. ZOOM_resultset_release releases a
1472 result set from a connection. The result set will be on its own
1473 thereafter; no operations on it will perform retrievals from a target.
1474 Only cached copies are returned.
1476 ZOOM C:fix case for HTTP servers responding with Connection:close.
1477 Ensure that if there is a current task it is resumed (like fetching
1478 more records in a result set) . Bug #3484.
1480 PQF parser: use odr_atoi for Odr_int (not atoi)
1482 Minor PQF encoding and decoding changes; reformat. PQF decoding: attribute
1483 values that contain any non-digits are treated as string attributes
1484 (previously decoding only checked for leading character ([0-9]). PQF
1485 encoding: attribute string values are not surrounded by double-quotes.
1487 --- 4.0.9 2010/05/21
1489 New utility for managing threads - thread_create.h.
1491 Add socket pipe utility - spipe.h. The socket pipe has same purpose as
1492 Unix pipe . Unfortunately Windows pipes do not work on select/poll -
1493 but YAZ' implementation do.
1495 Fixes for yaz_cond-functions on Windows 7.
1497 DLL export more symbols.
1499 zoomsh: show record do NOT render opac.
1501 Remove *.la files from Debian and RPM packages.
1503 --- 4.0.8 2010/05/11
1505 Debian package libyaz-dev depends on libgnutls-dev again (was
1506 removed in YAZ 4.0.6, but due to Libtool it is still needed
1507 even though yaz-config do not list libgnutls libs).
1509 ZOOM: Use only one WRBUF for returning string results for
1510 ZOOM_resultset. Reduces memory usage for ZOOM in general.
1512 ZOOM: ZOOM_connection do not use a shared pointer to
1513 ZOOM_resultset after ZOOM_resultset is destructed by
1514 user. Reverts to YAZ 4.0.4 behavior.
1516 --- 4.0.7 2010/05/04
1518 record-conv: fix problem with at least one XSL conversion -
1519 due to probably incorrect usage of XML XSL documents.
1521 --- 4.0.6 2010/04/29
1523 Fix yaz-config for static mode and the use of SSL (gnutls).
1525 --- 4.0.5 2010/04/29
1527 Forward decl timeval struct in mutex.h and gettimeofday.h.
1529 yaz-config: fix 'static' mode linking.
1531 --- 4.0.4 2010/04/28
1533 Add functions yaz_cond_{create,destroy,wait,signal,broadcast}. These
1534 are wrappers for pthreads or Windows. For Windows these are put in
1535 a separate DLL: yaz_cond4.
1537 libyaz.la (whole source) is compiled with thread. If thread support
1538 is enabled enabled, all source of YAZ is compiled with treading support.
1539 This allows core utilities such as yaz_log to use thread facilities.
1540 Previously (YAZ 3 and YAZ 4 releases), only libyaz_server.la was using
1541 thread utilities. This commit moves mutex utilities (mutex.c) from
1542 libyaz_server.la to libyaz.la.
1544 yaz-json-parse displays leading text until error.
1546 --- 4.0.3 2010/04/09
1548 Handle HTTP redirect for SRU GET in yaz-client and ZOOM C. Based on
1549 patch from Giannis Kosmas.
1551 SRU: no longer URL encode SRU database. The URL for an SRU server is
1552 a URL and such is alreeady encoded - at least when given with leading
1553 http:// or https://. This reverts behavior to YAZ 3.0.50.
1555 Support for new MARC XML notation TurboMARC which like MARCXML is a
1556 complete representation of MARC/ISO2709.. This one, however, is more
1557 compact and allows for faster processing with XSLT. TurboMARC can be
1558 used in the marcdisp.h API, from the yaz-marcdump utility and from
1561 yaz-ztest can be configured - via the database - to perform certain
1562 delays when it performs operations search, present and single record
1563 fetch. This allows testers to make yaz-ztest act as a real or even slow
1564 Z39.50 server. Refer to the yaz-ztest man pages for details.
1566 --- 4.0.2 2010/03/09
1568 wrbuf_destroy allows NULL WRBUF passed to it.
1570 Fix CCL qualifier aliases (did not work since YAZ 2.1.56).
1572 Add ZOOM_connection_close.
1574 No fixed size buffers for ZOOM shell - bug #3257.
1576 tstodr: make it work on s390 platform.
1578 New icu iterator-functions. The new icu_iter-functions makes it possible
1579 to use ICU chains from many threads.
1581 yaz-client: better syntax check for show command.
1583 --- 4.0.1 2010/01/26
1585 New glob file pattern utility. Like POSIX glob. For Windows too. Refer to
1588 New simple local-file XML include facility which allows file glob-patterns.
1589 Refer to yaz/xml_include.h.
1591 Utility yaz-json-parse which parses JSON and demonstrates the JSON parser
1594 ZOOM_record_get supports new parameter "format" which makes it format XML
1597 Fix JSON parser WRT start symbol. The start grammar symbol (referred to as
1598 JSONText in ECMA-262) is JSONValue, not JSONObject.
1600 --- 4.0.0 2010/01/20
1602 Windows binaries for YAZ now compiled with Visual Studio 2008 (VC9).
1603 Older versions of YAZ was compiled with Visual Studio 6.0 (1998).
1605 Update so/DLL to version 4. Windows version builds YAZ4.DLL.
1606 POSIX/Unix builds .so with major version 4.
1608 Remove old LOG_-defines from log.h. They have been obsolete and
1609 undefined by default for the last 5 years.
1611 Odr_int is now of type 'long long'. Used to be 'int' in YAZ 3 series.
1613 GFS: Remove socket (int *fd) from search_rr handler. The socket
1614 descriptor ptr is a facility that allowed a search handler to supply
1615 a socket which would serve as a callback - when search was complete.
1616 This facility has now been in use for years.
1618 COMSTACK API changes: cs_stackerr, cs_addrstr. COMSTACK method cs_stackerr
1619 removed. It is not implemented by tcpip or unix COMSTACK, perhaps for ISO
1620 SR which was removed 7 years ago. COMSTACK macro / method cs_addrstr now
1621 returns 'const char *' rather than 'char *. The returned string is
1622 read-only and should not be modified by applications. COMSTACK cs_close is
1623 now a void function - it no longer returns int. No applications check for
1624 the value and the implementations has always returned 0.
1626 ZOOM: use size_t for scan hit counts and str size. Functions
1627 ZOOM_scanset_term and ZOOM_scanset_display_term have changed, so that
1628 occ (hit count) and len (string length) are now of type size_t pointer
1629 rather than int pointer. This is to be able to represent large hit counts
1630 and to also just to use the proper type for string length (strlen result).
1632 New JSON parser. Refer to include/yaz/json.h .
1634 WRBUF API changes.. For size parameters for WRBUF size_t is now used ..
1635 Used to be int in some cases. Many wrbuf_-functions used to return an int
1636 indicating some length.. These return values were never used. And so they
1639 ODR: odr_malloc, odr_total now takes size_t for size.
1641 clone_z_type: fix leak; occurred for encoding failures.
1643 --- 3.0.52 2009/12/03
1645 tcpip comstack: fix use of uinitialized variable in cs_straddr. This
1646 bug was introduced in 3.0.51.
1648 --- 3.0.51 2009/12/02
1650 tcpip comstack: Remove TCP receiver buffer optimizations for Solaris.
1652 tcpip comstack: fix leak for getaddrinfo.
1654 Encoding of SRU database is performed by yaz_encode_sru_dbpath_odr or
1655 yaz_encode_sru_dbpath_buf. Now used by yaz-client and the ZOOM API.
1656 Decoding of SRU "path" database is performed by private function
1657 yaz_decode_sru_dbpath_odr . This in turn is used by yaz_srw_decode
1658 and yaz_sru_decode in server applications, GFS, yazproxy, metaproxy.
1660 yaz-client: honor base command for SRU. Change when database setting
1661 is applied for SRU and ensure it is kept when a connection is reset.
1662 Change also the way errors are displayed or SRU (decoding of packages).
1664 --- 3.0.50 2009/11/02
1666 Add support for extra request / response data for SRU codecs and GFS.
1667 The Z_SRW_PDU structure has two new members extraResponseData_{buf,len}
1668 for extra data response buffer and length. For the GFS, both request
1669 and response data (XML) is carried in extra_args and extra_response_data
1670 for the search handler. Patch by Ko van der Sloot.
1672 ZOOM: For queries that cannot be converted to the specified rpnCharset,
1673 ZOOM now returns a diagnostic on the client-side ('invalid query' /
1674 10010). This fixes bug #2113.
1676 yaz-client fix: If cmdfile is passed to yaz-client (option -f) and that
1677 cmdfile included a 'quit' command that would result in a memory violation.
1679 --- 3.0.49 2009/10/01
1681 Make a number of functions defined in xmlquery.c static. These have
1682 never been declared in a public header file (yaz/xmlquery.h) and was
1683 made public by mistake.
1685 Improve speed of character conversions (iconv utilities). This makes
1686 conversions from MARC-8 faster.
1688 ZOOM_record_get returns 0 pointer if a MARC record can not be decoded -
1689 unless type desired is "raw". This will prevent type "xml" from
1690 returning ISO2709 .. Which obviously can not be XML parsed.
1692 Fix memory leak in ZOOM that would occur if option apdulog was used
1693 on a re-used connection.
1695 Frontend server logs HTTP requests.
1697 Frontend server now sends Z39.50 close when it times out (sesssion has
1698 been idle for too long). Versions 2.0.30 and earlier also sent close.
1699 But due to a mistake this was disabled in all versions after that, i.e.
1700 the server would just close the socket immediately.
1702 yaz-client emits a better message when receiving an unrecognised
1703 userInformationField.
1705 Skip zero-length subfields when decoding ISO2709. This rare case happens
1706 if a record has two FS characters in a sequence. Without this patch
1707 there would be a reference beyond char array in using_code_len fragments
1710 Fix yaz-marcdump error that would occur if option -n was used (bug #3028).
1712 --- 3.0.48 2009/08/28
1714 The show command offered by the zoomsh command now takes a 3d optional
1715 parameter type which is what is passed to ZOOM_record. If the type
1716 argument is omitted, "render" is used.
1718 RPN to CQL conv may use USE string attributes (bug #2978).
1720 MarcXchange NS is now info:lc/xmlns/marcxchange-v1 .
1722 --- 3.0.47 2009/07/08
1724 Function yaz_xml2query allows a diagnostic element in the PQF XML
1725 representation .. diagnostic@code and diagnostic@addinfo is diagnostic
1726 code and additional info respectively.
1728 The BER BOOLEAN is now the integral type Odr_bool which still happens
1729 to be an 'int'. The BER INTEGER which used to be a plain 'int' is now
1730 typedef'd to Odr_int. This is still an integral 'int', but it may be
1731 changed to 64-bit via a one-liner in nmem.h (NMEM_64=1). The documentation,
1732 ASN-1 compiler as well as programs has been updated to use the new types.
1734 --- 3.0.46 2009/06/08
1736 zoom: ZOOM_record_get now renders OPAC records when type=xml. Previously
1737 only the bibliographic record was rendered. For type=opac, an OPAC
1738 record is only returned if it is present.
1740 iconv: small fix for encoding of advancegreek.
1742 yaz-client: avoid double display of SRU/SRW records (bug #2798).
1744 yaz-client: option auto_reconnect=on really reconnects.
1746 yaz-client: fix bug #2770 - avoid length limit for auth parameters.
1748 server: avoid null ptr ref for for yaz_poll errors.
1750 build: fix RPM build for RHEL 5.3.
1752 comstack: prefer IPV6 addresses over IPV4 - should refix bug #2350
1754 --- 3.0.45 2009/03/31
1756 Fixed bug #2709: TCP connect returns Invalid argument.
1758 Fixed compilation for mingw.
1760 Honor charset for raw records (ZOOM_record_get).
1762 Fixed use of errno for threaded mode that was seen on Solaris 10.
1764 Fixed argument passing with blanks in value for Windows Service.
1766 Disable YAZ' own log rotate by default (no 1 GB limit).
1767 The variable l_max_size which specifies the log file limit is set to 0
1768 (DISABLED): This is due to the fact that YAZ is most often deployed using
1769 logrotate. Also YAZ can not perform log rotate because of unsufficient
1770 permissions (setuid).
1772 --- 3.0.44 2009/02/17
1774 List supported encodings in man page for yaz-iconv.
1776 Fixed missing SSL libs for --libs output
1778 Re-established OID record syntax application-xml. Nobody should use it
1779 but we don't want to change soname because of this symbol being absent.
1781 --- 3.0.42 2009/02/02
1783 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
1785 Added member named_result_sets for init handler struct for the GFS. This
1786 allows a server to disable named result sets.
1788 Removed OID record syntax application-xml.
1790 Added support for rule-based transliterator for ICU wrapper of YAZ.
1792 Fixed bug #1902: yaz-icu XML output.
1794 Make YAZ checks Emacs friendly.
1796 BITSTRING value shows value. Bug #2346.
1798 ISO2709 decoding: skip control characters from indicator data.
1800 Omit sort key by default in yaz-icu's output.
1802 Allow combined single char options (again) for YAZ' options function.
1804 Utility yaz-marcdump got option to display YAZ version (-V).
1806 Allow YAZ to use ICU 3.4.
1808 Added new ICU test case which illustrates removal of diacritics.
1810 --- 3.0.41 2008/12/29
1812 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
1814 --- 3.0.40 2008/12/29
1816 For configure, using option --without-xml2 also disables Libxslt/Libexslt
1819 Fixed bug #2352: yaz-marcdump crashes for certain record.
1821 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
1823 Added support for Danmarc2 to UTF-8 conversion.
1825 Added support for ISO5426 to UTF-8 conversion.
1827 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
1828 implementation version.
1830 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
1832 --- 3.0.38 2008/11/10
1834 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
1835 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
1837 ZOOM C now interprets databaseName option for ZOOM connection as path
1840 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
1842 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
1844 Dummy Libxml2 types no longer defined in headers of YAZ'.
1846 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
1849 --- 3.0.36 2008/09/26
1851 Various ODR chapter fixes.
1853 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
1855 Added missing source for Windows compilation, mutex.c.
1857 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
1859 For SRU connections in ZOOM all records up to "count" are now fetched.
1861 Fixed crash in generic frontend server (and yaz-ztest) which occurred
1862 in Windows due to bad error handling for Libxml2.
1864 Added facility for sending arbitrary records (ASN.1 any) using
1865 ZOOM C's Extended service update. Patch by Sam Reynolds.
1867 New options for ZOOM C's connection, logapdu which makes ZOOM log
1870 --- 3.0.34 2008/06/18
1872 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
1874 --- 3.0.32 2008/06/12
1876 Fixed memory violation that could occur when decoding UTF-8. This bug
1877 was only present in 3.0.30 of YAZ.
1879 --- 3.0.30 2008/06/06
1881 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
1882 GNU TLS is used by default (if found).
1884 yaz-ztest returns OPAC records if a client asks for OPAC.
1886 Improved speed of MARC-8 encoding.
1888 Added support for lossy and loss-less MARC-8 encoding.
1890 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
1892 Added new Windows Service wrapper (sc).
1894 yaz-client's itemorder command may now send a file.
1896 Fixed yaz-marcdump to allow the use of NS prefix for record element.
1898 Added new function yaz_log_xml_errors.
1900 Allow (but warn) unknown XML attributes in MARCXML parsing.
1902 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
1904 The UTF-8 to MARC-8 conversion now uses a different set of characters
1905 for Greek symbols. Bug #2120.
1907 --- 3.0.26 2008/02/21
1909 Added yaz_daemon (daemon.h).
1911 Fixed bug #2068: pkg-config trouble
1913 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
1915 --- 3.0.24 2008/01/28
1917 Document --with-xml2 option.
1919 Added OPAC XML XSD (etc/opacxml.xsd).
1921 Allow glob mask for name attribute in retrieval element for the
1922 generic frontend server's retrieval facility.
1924 Changed yaz_poll_poll to return yaz_poll_except for all returned events
1925 except POLLIN/POLLOUT.
1927 Fixed error handling in cs_listen. Bug #2037.
1929 --- 3.0.22 2008/01/20
1931 Fixed version in yaz/yaz-version.h.
1933 Fixed bug #2027: Crash when closing connection.
1935 Changed configure so that ICU support is only enabled if only ICU
1936 and Libxml2 is available (because the ICU chain is XML based).
1938 --- 3.0.20 2008/01/15
1940 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
1941 is built. Only this DLL depends on the ICU runtime.
1943 yaz-ziffy is no longer part of YAZ. It is distributed separately by
1944 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
1946 Changed license of CCL module to 'Revised BSD'. After consultation with
1947 remaining members of the original EUROPAGATE consortium, we are re-issuing
1948 the CCL module without a separate license. The software was developed by
1949 Index Data as part of a research project. The special license was included
1950 to help feed usage information back to the project consortium to support
1951 project evaluation. At this time, the project consortium has long-since
1952 disbanded, and the majority of the original principals have retired. At the
1953 same time, we have significantly modified the software during the following
1954 years, to the point where very practically no original code remains. To
1955 simplify re-use of the software, we have contacted those members of the
1956 consortium who could be reached, and agreed to re-issue the module as a
1957 proper part of the YAZ package.
1959 Tcl scripts uses /usr/bin/tclsh as preferred shell.
1961 CQL closer to being version 1.2 compliant. CQL also allows free-form
1962 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
1965 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
1966 bug could make Extended services handling crash in the ZOOM layer. This
1967 bug was only present in YAZ 3.0.18.
1969 --- 3.0.18 2007/12/19
1971 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
1974 yaz-marcdump reads and writes collection wrapped records.
1976 Handle OPAC for record conversion module.
1978 Fixes for ICU wrapper.
1980 Allow ICU libs to be controlled with --with-icu .
1982 --- 3.0.16 2007/11/12
1984 Added yaz_poll which is a wrapper for select/poll. When poll is available
1985 and non-buggy, it is used, by yaz_poll . This allows more than 1024
1986 sockets to be in use.
1988 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
1989 functionality through an XML based configuration (ICU chain). This system
1990 is useful for search facilities such as Pazpar2 and Zebra that needs to
1991 perform tokenization of indexed material. The ICU code in a separate
1992 library libyaz3_icu.a.
1994 Added HTTP tunnel facility for COMSTACK, bug #1752.
1995 This is a facility that allows a Web proxy, such as squid, to tunnel
1996 Z39.50 traffic. This facility is "transparent" to must applications
1997 using YAZ. It's enabled by using pseudo transport connect: followed by
1998 the proxy address, followed by command, then follwed by he regular
1999 "virtual" addresss. For example,
2000 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
2002 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
2004 --- 3.0.14 2007/09/21
2006 Fixed bad memory reference in ZOOM_record - cuased by member not being
2007 initialized. This was a problem only in YAZ 3.0.12.
2009 Fixed bug in conversion from MARC to XML: Non-XML characters in control
2010 fields were not removed.
2012 Changed the way C code is generated from codetables.xml. Made a MARC-8
2013 conversion trie for each characterSet section rather than codeTable.
2014 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
2015 of codetables.xml from Larry Dixson, LOC. Bug #1464.
2017 --- 3.0.12 2007/09/12
2019 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
2020 from ZOOM_record_error).
2022 ZOOM C function ZOOM_record_get returns record schema for type="schema".
2024 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
2026 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
2028 Better SRW-to-Bib-1 diagnostic mapping.
2030 ZOOM C and yaz-client announces SRU version 1.2 by default.
2032 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
2035 Fixed in yaz_sru_decode to allow other version than 1.1.
2037 --- 3.0.10 2007/08/22
2039 Added support for SRU scan for ZOOM.
2041 Added support for the use of the older versions or Extended Service
2042 Update in ZOOM. To faciliate this, an option "updateVersion" may be
2043 set to the version , 1=first, 2=second, 3=third. The third version is
2044 what ZOOM C has used so far. And that, obviously, is the default.
2046 Added support for CCL queries in Z39.50 queries sent to the GFS (and
2047 therefore in Zebra and in SimpleServer-based applications). The new
2048 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
2049 qualifier file used to transform incoming CCL queries into Type-1 RPN,
2050 which is passed into the back-end search callback function.
2052 Added support for HTTP Basic authentication in clients: the SRU/W
2053 codec encodes the username/password elements of the PDU structure
2054 appropriately, and these may be set using the "user" and "password"
2055 options in ZOOM-C applications (the same options that are used for
2056 Z39.50 authentication).
2058 --- 3.0.8 2007/06/25
2060 Fixed bug #1208: SSL appears to be broken in ZOOM.
2062 Fixed bug #1206: Libxml2 include path weirdness.
2064 Added oid_name_to_dotstring.
2066 Allow elementSetName to be specified for ZOOM C record update.
2068 Allow waitAction to be specified for ZOOM C based for Extended Services.
2070 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
2071 syntax OID. Bug introduced in YAZ 3 series.
2073 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
2075 --- 3.0.6 2007/06/06
2077 Fixed bug #1157: yaz-client does not read .yazclientrc from current
2078 directory. yaz-client now reads commands from file given by option -f
2079 if specified; then tries to read .yazclientrc in current directory.
2080 Failing that, it reads .yazclientrc from user's home directory.
2082 Added support for correlationInfo Note and ID for Record Update via
2085 Added yaz-client command querycharset which specifies character set for
2086 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
2087 (termListAndStartPoint).
2089 Charset ISO5428:1984 is an alias for ISO5428-1984.
2091 Implemented a way to perform scan in a result set using Z39.50. This
2092 is achieved by attaching the result set name in the characterInfo
2093 (type InternationalString) of OtherInformation in the Scan Request PDU.
2094 The result set is identified in the otherinformation by the new OID:
2095 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
2096 This allows for scan in result set and faceted search . Zebra did some
2097 of this in the APT term using attribute type 8 and value being result
2098 set. Using the OtherInformation approach for this is cleaner and easier
2099 to work with in proxies and the like. This facility can be used in
2100 yaz-client using new command setscan which takes a result set as first
2101 argument, start position (APT) as second.
2103 Changed decoding of SRU XML packed records to deal with servers that
2104 have recordData with XML data with multiple root nodes. Also make
2105 comparison for recordPacking case insensitive. Again, one server
2106 returns "XML" where others return "xml".
2108 For SRU responses allow Content-Type application/xml as well as text/xml.
2110 --- 3.0.4 2007/05/21
2112 Fixed bug in character set conversion of BER strings. Bug introduced
2115 --- 3.0.2 2007/05/08
2117 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
2119 For OID class, use oid_class consistently.
2121 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
2124 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
2125 character set for bibliographic information interchange". By Giannis Kosmas.
2127 Added documentation on new OID API.
2129 --- 3.0.0 2007/05/02
2131 Changes to generic frontend server interface: added new member
2132 'query_charset' for bend_initrequest structure. A backend init handler
2133 should set this member to its native character set for query terms.
2134 When defined, the frontend server logic will announce this character set
2135 to a client if the negotiationModel bit is set by the client. All server
2136 implementors are encouraged to specify this. If a backend server does not
2137 specify this a warning is issued using yaz_log(YLOG_WARN,..).
2139 Added CCL utility to remove terms (stop words) from resulting RPN
2140 tree. This is handled by functions with prefix ccl_stop_words_ .
2142 New ZOOM C option, "rpnCharset", which allows client-side conversion of
2143 terms in RPN queries.
2145 Clean-up the CCL API. Moved some internal structures from ccl.h to
2146 private header cclp.h. Changed ccl_parser_create so that a Bibset must
2147 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
2148 This is replaced by ccl_parser_find_str which takes a string instead.
2150 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
2151 libyaz.la is the core of YAZ except the generic frontend server and
2152 does not depend on POSIX threads anymore. libyaz_server.la is the
2153 generic frontend server facilities and uses POSIX thread functionality
2154 if available. The libyaz.la no longer depends on POSIX threads because
2155 the number of global structures is limited. NMEM no longer re-uses blocks
2156 between threads ; it simply free's memory immediately but allocates in
2157 "large" chunks as usual. We don't expect any performance penalties
2158 because of this. The yaz_log system is still using a global log_level so
2159 caution must be taken when modifying it with yaz_log_init_.. +
2160 yaz_log_mask_str. This, however, should not cause any trouble because
2161 these functions are called during initialization of application code
2162 anyway. `yaz-config --libs server` returns libs for server applications;
2163 `yaz-config --libs` returns libs for non-server applications.
2165 New OID database - with public definitions in oid_db.h. Removed old OID
2166 database including the head oid.h and definitions such as enum oid_value
2167 and struct oident. The new OID database uses the same string names as
2168 before but the 'protocol' is gone. There are now only two representations
2169 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
2170 converts from string to OID; functions with prefix yaz_oid_to_string
2171 converts the other way.
2173 Change to emit_term() in CQL-to-PQF query translation: when a term has
2174 the /regexp relation modifier, do not process it for leading and
2175 trailing "^" and "*", which have quite different meanings in regular
2178 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
2179 write handlers no longer carries a 'last' parameter. This will make
2180 yaz_iconv flush "less" characters. A flush is performed by call to
2181 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
2183 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
2184 removed, because function yaz_query_to_wrbuf does the same.
2186 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
2187 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
2189 Deprecated MARC utility functions removed.
2191 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
2194 Branch split: YAZ_2_1_55_branch
2196 --- 2.1.54 2007/03/16
2198 Fix to ZOOM-C so that transparent reconnection is properly handled on
2199 connections that are in asynchronous mode.
2201 Fixed compilation on OpenBSD 4.0.
2203 Large strings in GRS-1 records are now properly displayed in yaz-client.
2205 Added character conversion support for "advancegreek"; based on patch from
2208 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
2209 sequence is met. Before the error was not set so it would be unknown.
2211 Adjust yaz-marcdump MARC reader so that it skips until record separator
2214 --- 2.1.52 2007/03/07
2216 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
2217 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
2218 fd_set structure used as a bitmask for the FDs to be selected on.
2220 Using ACX_PTHREAD macro to check for POSIX threads.
2222 Fixed have-vsnprintf check.
2224 --- 2.1.50 2007/02/23
2226 Fixes for configure on BSD. Bug #900.
2228 Added snprintf/vsnprintf wrappers for systems that don't have
2229 limits (heavens forbid).
2231 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
2232 created before all previous tasks were completed and removed from the
2233 task queue, the new task could be removed by a mistake.
2235 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
2237 Implemented pass-through CQL-to-PQF conversions. Bug #861.
2239 Fixed bug #832: Problem with MARC/charset in yaz-client.
2241 Fixed bug #668: save command line history for yaz-client.
2243 Fixed bug #830: pkg-config support.
2245 --- 2.1.48 2007/01/23
2247 Extended ZOOM result set options with two options that may be read by
2248 a client: resultSetStatus and presentStatus with values as specified for
2250 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
2252 Fixed bug #827: Using SSL fails on Debian etch.
2254 Fixed bug #826: Weird looking chars for set of MARC records.
2256 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
2257 that is treated as an ItemOrder with itemRequest being an XML document
2258 external. The value of "doc" is the content.
2260 Extended the GFS search facility. New member of bend_search_rr
2261 'estimated_hit_count' signals that hits is known to be an estmate
2262 (higher or lower than real hit count). New member 'partial_resultset'
2263 signals that the search was partial (hit count is lower or equal than
2264 real hit count). For Z39.50, the information is stored in resultSetStatus
2265 member of SearchResponse APDU. For SRU, the information is signalled
2266 via SRU diagnostic 59: "Result set created with valid partial results
2269 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
2271 --- 2.1.46 2007/01/13
2273 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
2275 Added ZOOM_connection_peek_event.
2277 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
2278 the following new functions:
2279 ZOOM_event_nonblock, ZOOM_connection_process,
2280 ZOOM_connection_get_{socket,mask,timeout},
2281 ZOOM_connection_fire_event_{timeout,socket}.
2282 The existing blocking event handler, ZOOM_event, is a wrapper for the
2283 + blocking ZOOM_event_sys_{poll,select}.
2285 Implemented function ccl_xml_config which parses XML version of CCL
2286 configuration (bug #798).
2288 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
2290 Added timings utility (yaz/timing.h)
2292 --- 2.1.44 2007/01/03
2294 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
2297 Fixed bug #779: Rotation of apdu.log fails.
2299 Fixed for character set conversions:
2300 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
2301 Honor G1 set in MARC-8 decoding.
2303 --- 2.1.42 2006/12/17
2305 Fixed bug #775: char conversion does not handle Alternative UTF-8
2308 Implemented function yaz_marc_read_line which parses MARC line format
2309 records. There is a wealth of formats out there. So far, this function
2310 reads line records produced by yaz_marc_write_line.
2312 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
2313 more generic and easier to remember(!) options: -i format and -o format
2314 which specifies input format and output format respectively - where
2315 format is one of "marc", "marcxml", "line", "marcxchange".
2317 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
2318 does not print anything except warnings for records.
2320 For yaz-marcdump, added support for MARC split into files (-s) with a given
2323 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
2324 spec, at http://www.loc.gov/standards/sru/record-update/
2325 This has changed the binary layout of the following structs:
2326 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
2327 bend_update_rr . Patch by Ko van der Sloot.
2329 Added GFS utility function bend_assoc_is_alive which returns 1 if
2330 association is still alive (client is connected); 0 otherwise (client
2331 closed connection). This allows busy servers to stop working for
2334 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
2335 been a separate piece of software. This version of ziffy has been modified
2336 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
2338 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
2340 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
2341 Client code may now interrogate options such as "init_opt_sort" to
2342 find out whether the server claims to support various options.
2344 --- 2.1.40 2006/11/27
2346 Added utilities yaz_{set,get}_esn to set/get element set name from
2349 Removed the build of libyazthread.la. The libyaz.so is the threaded version
2350 of YAZ and has been so since YAZ 2.1.10.
2352 Implemented ZOOM_record_error which returns error information for
2353 record (surrogate diagnostic).
2355 --- 2.1.38 2006/10/31
2357 Updates for SRU Update by Ko van der Sloot:
2358 1. Changed name from "operation" to "action"
2359 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
2360 versions in the code, marked as 'backward compatible'.
2361 3. Added diagnostics for SRU Update.
2363 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
2365 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
2367 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
2369 For GFS, fixed problem with SRU diagnostic 'First record position out of
2370 range' being issued for 0 hits.
2372 zoomtst10 part of Windows Build.
2374 --- 2.1.36 2006/10/13
2376 Implemented yaz_filepath_comp which splits a path into file path
2377 components (required by Zebra 2.0.3+).
2379 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
2380 BSD inspired license until now so this should not have any real impact on
2381 anybody. See http://www.opensource.org/licenses/bsd-license.php
2383 Fixed bug #687: Missing log lines.
2385 Fixed bug #678: CQL to PQF translation does not preserve double-quote
2388 Fixed bug #689: SRU diagnostics to be added.
2390 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
2391 whether a connection is idle (no more work do do).
2393 --- 2.1.34 2006/10/04
2395 Change type of optval from long to int for invocation of setsockopt with
2396 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
2398 Added support for specifying the max log file size for the Generic
2399 Frontend Server. The size is given with option -r.
2401 --- 2.1.32 2006/09/21
2403 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
2405 --- 2.1.30 2006/09/17
2407 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
2410 Fixed bug in Generic Frontend Server that could cause a server to stop
2411 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
2413 For the generic frontend server, the maximum record size is used as maximum
2414 size of incoming packages (SRU + Z39.50). The value until was previously
2415 only used in Z39.50 Init negotiation and, later, in a session controlled
2416 sizes of records returned. This is controlled using -k option. It can be
2417 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
2419 --- 2.1.28 2006/09/04
2421 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
2424 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
2426 New option for yaz-marcdump -lpos=value which allows setting a portion
2427 of MARC header to a certain value.
2429 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
2431 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
2432 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
2434 --- 2.1.26 2006/08/15
2436 Fixed problem with SRU mode type (soap, get, post) for yaz-client
2439 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
2441 --- 2.1.24 2006/08/08
2443 Fixed MARC ISO2709 encoding routines to deal with character set
2446 Minor changes to GFS logging. Database included in search request log
2449 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
2450 cached/multiple records.
2452 Shared libraries are built by default on Unix+configure.
2454 Changed cql2pqf transformation to use a different evaluation order. The
2455 new order is: always, relation, structure, position, truncation, index
2456 and relationModifier. Old order was: always, relation, relationModifier,
2457 structure, index, position, truncation. Note that the the latter ones
2458 override former ones for identical attributes.. The new scheme means that
2459 it is possible to override any existing attribute with a relationModifier.
2460 And also that it is possible to override everything for the index rule
2461 (except the ones listed in relationModifier). No order is perfect but this
2462 one, we believe, covers more real cases.. The "always" should have been
2463 called "default", since the attributes there can be overridden with all
2466 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
2467 compilation phase, but also for yaz-config --cflags output. This allows
2468 us to have public headers with Libxml2 stuff in them . It should also,
2469 eventually, make Libxml2 checks redundant in packages using YAZ, such
2472 --- 2.1.22 2006/06/15
2474 Changed SRU update structure bend_update_rr so that SRU diagnostics are
2475 stored in uri, message and details.. Previously diagnostics were stored
2476 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
2477 compatibility.. but he's probably the only one affected, so.
2479 Added support for CCL, compiled on the client side, in ZOOM-C. This
2480 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
2481 input; the resulting query objects can be used for for searching with
2482 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
2484 YAZ' configure searches for OpenSSL by default.
2486 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
2487 SL_CTX_use_certificate_file. See
2488 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
2489 for more info. Thanks to Ko van der Sloot.
2491 --- 2.1.20 2006/06/02
2493 Bug #600: SRU GET, POST support for yaz-client. Introduced
2494 command 'sru' which selects method SOAP/GET/POST.
2496 Allow missingValueAction to be specified for the sortspec string -
2497 function yaz_sort_spec. By default, the missing value action is null.
2498 Use ! to specify "abort". Use = followed by stringvalue to specify default
2501 Ensured that Present-handler (if defined) is called in GFS before any call to
2502 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
2503 searchRetrieve requests.
2505 Documentation for YAZ is now based on the Docbook XML/XSLT using
2506 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
2507 is no longer depending on jade/openjade or docbook-to-man scripts.
2508 PDF is no longer part of the distribution - but can optionally be
2509 made using DSSSL/jadetex or FOP.
2511 Added retrieval handling support in Generic Frontend Server to support
2512 conversion between MARC/XML as well as XSLTtransforms. See
2513 etc/yazgfs.xml for an example.
2515 Added Authentication support to Generic Frontend Server in SRU
2516 mode. Authentication using HTTP Basic is supported, as is the use
2517 of 'x-username' and 'x-password' parameters in the request itself.
2519 Added support for a new character set MARC8s identical to MARC8 except
2520 that it converts combined characters to single Unicode characters in the
2521 Latin-1 range (when possible).
2523 --- 2.1.18 2006/04/24
2525 ASN.1 compiler 0.4: generates brief Doxygen file header for
2526 generated .h/.c files.
2528 Utility yaz_iconv now supports conversion to MARC-8.
2530 New facilities for the MARC module. The reading - and writing of
2531 content are separate methods for the yaz_marc_t handle. The following
2532 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
2533 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
2534 format). Write functions have prefix yaz_marc_write_.. The existing
2535 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
2536 available. Removed support for OAI-MARC and simplexml (not the
2537 simplexml from PHP5).
2539 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
2540 to be returned for this connection.
2542 --- 2.1.16 2006/03/31
2544 Allow multiple languages and charsets to be specified with
2545 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
2546 negcharset iso-8859-1,utf-8
2548 Translation of proximity nodes from CQL into PQF now works.
2550 Moved to automake 1.8, 1.9.
2552 Added function yaz_log_set_handler which allows a log handler to be
2553 installed. This handler will be called for all log messages. Output
2554 to file is also produced; but that can be disabled by passing NULL
2555 fname to yaz_log_init_file.
2557 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
2559 For SRW (including GFS), accept application/soap+xml as content-type
2562 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
2563 produces NO stylesheet reference even if a default stylesheet is specified
2566 --- 2.1.14 2006/03/14
2568 Updated Windows package to include yazd.dll + yazd.lib for the
2569 Development component.
2571 If the environment variable YAZ_LOG is set, then it is used as a
2572 string indicating the default level of logging to use if not
2573 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
2574 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
2575 used as before. So, for example, to omit warnings from YAZ logging,
2576 export YAZ_LOG=-warn
2578 cql_transform() now map structure and other attributes before indexes,
2579 so that index-specific structures and other attributes can override
2580 defaults. So now a combination of mapping specifications such as:
2582 index.dc.date = 1=date-modified 4=5
2583 does the right thing.
2585 cql_transform() now also respects the "always" mapping specification,
2586 which establishes an initial set of attributes to be used for all
2587 terms except where overridden by more specific attributes associated
2588 with the index, relation or modifier.
2590 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
2591 which mode to use; one of "post", "get" or "soap" (SRW, default).
2593 Fixes for yaz_iconv routines: changed trie-based character set conversions
2594 to use only non-negative values for bit fields due to Sun's C compiler not
2595 supporting negative values.
2597 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
2598 sequences where not read correctly. Fix by Rustam Usmanov.
2600 Updated win/makefile to use options, settings which makes things
2601 compile with VS C 2005.
2603 --- 2.1.12 2006/02/01
2605 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
2607 In ZOOM socket code, use select instead of poll on MacOSX.
2609 ZOOM-C now support client-side compilation of CQL into RPN that is
2610 sent to the server, enabling CQL to be used against all Z39.50
2611 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
2612 ZOOM_query object, and submit it using ZOOM_connection_search().
2613 The CQL-to-RPN translation uses a configuration file, the name of
2614 which must be specified in the Connection's "cqlfile" option.
2616 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
2617 function, which takes as its start-term parameter a ZOOM_query object
2618 (which may have had either CQL or RPN set into it).
2621 --- 2.1.10 2005/11/29
2623 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
2624 GFS to support this as well. Backend handler, bend_srw_update, does the
2625 update work. Code contributed by Ko van der Sloot.
2627 Allow retrieval of Search Result-1 information in ZOOM by the use of
2628 options that are attached to a result set. ZOOM documentation updated
2631 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
2632 UTF-8 conversion. Patch by Raj Patel.
2634 Added option -m to GFS to control formatting of timestamps in log file.
2636 Added 'exit' as synonym for 'quit' in yaz-client
2638 Added support for specifying SRW resultSetId + resultSetIdleTime in a
2639 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
2640 for the new members. Patch by Ko van der Sloot.
2642 Added support for SRU POST. It is supported for content-type
2643 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
2645 Do not build the separate Multi-threaded (MT) library libyazthread.la.
2646 Instead make the library libyaz.la multi-threaded. Threading as a whole
2647 can still be disabled by configure option --disable-threads. Previosly,
2648 with older GLIBCs there were problems with MT libs under Apache. This
2649 has now been fixed a long time ago.
2651 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
2654 CQL module modified to be case insensitive for relations/indexes/operations.
2656 Fixed bug in CQL transform code: incorrect value relationModifieder
2659 Added 'show all' command for yaz-client which retrieves all results
2662 Added new yaz-client, xmles, which takes a (private) OID and
2663 a document to be sent as an extended service request.
2665 Describe new yaz-client commands wait_response and set_auto_wait.
2667 Increase TCP/IP listener backlog from 3 (which I am guessing was
2668 copied from the SunOS manual entry way back when) so SOMAXCONN, so
2669 that the socket will queue as many incoming connections as it's able
2670 to handle ongoing connections. In other words, it will never now
2671 refuse a connection that it would be able to handle merely because
2672 it's not got around to accepting() enough of the pending connections
2673 yet. This is the behaviour anyway under Linux, where the listen()
2674 argument is ignored; but not under BSD and on systems such as
2675 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
2676 YAZ-based servers should now be uniform across operating systems in
2679 yaz-marcdump uses 64-bit file access on some systems. This is enabled
2680 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
2681 This allows yaz-marcdump to read large MARC batches (>2 GB).
2683 Modified all YAZ source files - except the source which is auto-generated
2684 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
2687 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
2688 corresponding to the existing *_setl() function. These allow option
2689 values containing arbitrary valuues.
2691 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
2692 ZOOM_resultset_sort() in new applications. Its behaviour is identical
2693 except that it returns an indicator of whether or not the sort
2694 criterion was accepted (0 for OK, -1 for invalid).
2696 --- 2.1.8 2005/06/07
2698 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
2699 MARC output rather than returning "new" buffer.
2701 yaz-client warns about unknown init options.
2703 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
2705 --- 2.1.6 2005/05/24
2707 Added support for SRW sort in Generic Frontend Server. Patch
2708 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
2709 sortKeys - or NULL if none is provided.
2711 Fixed bug #307: It was impossible to specify indefinite/no timeout
2712 for ZOOM_event. Special timeout value -1 now means indefinite timeout
2715 Added support for multiple languages and charsets to be specified in
2716 ZOOM. Each charset/language is separated by a blank. If negotiation is
2717 in effect in init-response, Option
2718 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
2719 Code based on patch by Vasiliy Osadchuk.
2721 Fixed bug #306: infinite recursion that occurred when calling
2722 yaz_log_level_init as the first call (before other log level or
2725 Fixed bug in scan handling in front end server: if preferred-Position-In-
2726 Response was non-present, a NULL pointer referece was performed.
2728 --- 2.1.4 2005/04/26
2730 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
2731 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
2732 now defined for all those error codes. So instead of putting 109 in
2733 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
2734 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
2736 Modified the yaz-marcdump utility to skip garbage bytes between MARC
2739 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
2741 Program yaz-client now exits and produces an error message if multiple
2742 Z39.50 servers are specified on the command line (none or one allowed
2745 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
2748 --- 2.1.2 2005/03/16
2750 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
2752 Fixed bug #272: Preserve spacing for CCL terms.
2754 --- 2.1.0 2005/03/14
2756 Added support for virtual hosts and multiple backend servers for
2757 the YAZ frontend server. The configution is XML based and
2758 support specificition of CQL to RPN mappings and explain information.
2759 See section "Virtual Hosts" in the YAZ manual.
2761 Extended OPAC display utility. OPAC display utility renders
2762 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
2763 to supplement yaz_marc_decode_wrbuf.
2765 Fixed a bug in MARC decoder that could caused it to crash for some
2766 invalid MARC records. More diagnostics and warnings where added in
2767 XML output (warnings, etc are stored in comments).
2769 --- 2.0.34 2005/02/08
2771 Fixes for UNIX domain sockets. Bug #261.
2773 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
2775 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
2776 Added yaz_marc_subfield_str which defines subfield lead string which is
2777 used in YAZ_MARC_LINE format. Default string is blank+$. Added
2778 yaz_marc_endline_str which defines end of fields string used in
2779 YAZ_MARC_LINE format. Default string is newline.
2781 Experimental support for MarcXChange. This format can be produced
2782 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
2783 http://www.bs.dk/standards/MarcXchange.xsd
2785 Added yaz-client commands scansize that sets maximum number of
2786 entries to be returned by scan.
2788 --- 2.0.32 2005/01/11
2790 Added support for SRW scan in yaz-client and Generic Frontend Server.
2792 * Added whereInList member to SRW Scan Term.
2794 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
2796 Fixed NMEM system to return aligned blocks on the smallest boundaries
2797 that are suitably aligned for all possible types on the particular
2798 architecture YAZ is being built for.
2800 --- 2.0.30 2005/01/04
2802 Fixed numerious warnings that was issued with newer versions of GCC.
2804 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
2805 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
2808 Make YAZ Generic Frontend Server slightly faster.
2810 Enhance (and reduce) logging for Generic Frontend Server.
2812 Revert YAZ log system so that it flushes every write operation
2813 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
2815 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
2816 instead of LOG_, due to name clash with syslog(3). LOG_ are still
2817 present. New applications should define YAZ_USE_NEW_LOG=1 - this
2818 will effectively disable old definitions.
2820 --- 2.0.28 2004/11/09
2822 Added yaz_log_time_format which specifies log format using
2825 Added yaz_log_module_level which returns mask for a module. Value
2826 is non-zero mask a if module is enabled; zero if disabled.
2828 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
2829 in include/yaz/cql.h.
2831 Fixed bug #176: Dont throw diagnostics on empty SRU args.
2833 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
2835 Fixed bug #172: RPM builds does not enable SSL.
2837 Doxyfile.in part of dist. Doxyfile generated by configure.
2839 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
2840 are given and the corresponding component does not exist.
2842 Extend CCL documentation in YAZ reference. Describe r=r.
2844 --- 2.0.26 2004/10/01
2846 Fixed MARC->MARCXML conversion to properly deal with
2847 fields, subfields, indicators having non-ASCII characters.
2849 Fixed MARC->MARCXML conversion so that ASCII control characters
2850 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
2853 Added YAZ GFS support for conversion from Z39.50 surrogate
2854 diagnostics to SRW surrogate diagnostics.
2856 Bug fix: YAZ GFS did not return schema in explainResponse.
2858 --- 2.0.25 2004/09/30
2860 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
2861 now converts recordSchema to elementSetName as well as schema URI.
2863 Fixed bug in COMSTACK that prevented HTTP request packages from being
2866 --- 2.0.24 2004/09/29
2868 Added CCL facility r=r "range" which is similar to r=o "ordered" but
2869 does not require white-space before and after the dash in a range, e.g.
2870 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
2873 Fixed a few AC_TRY_LINK configure tests that did not operate properly
2874 due to new GCC removing "redundant" code.
2876 Added yaz-client commands scanpos and scanstep that sets preferred
2877 position and step-size for scan.
2879 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
2881 Added CCL utility ccl_qual_buf which parses one or more CCL
2882 spec lines in a buffer.
2884 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
2885 of name and value - ignoring empty lines and comments.
2887 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
2889 Added odr_get_element_path which returns current element path for an
2890 ODR handle. This utility is useful in error handling or user-defined
2893 Added ODR_PRINT utility odr_set_stream which is is a more generic
2894 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
2895 to a write function and pointer to close function. The close function - if
2896 non-NULL - will be called during odr_destroy.
2898 Fixed bug in CCL parser where truncation char was not removed from
2899 right side when truncation=both was in effect.
2901 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
2904 --- 2.0.23 2004/08/11
2906 Fix buffer overrun in CQL parser when dealing with proximity (%).
2908 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
2909 to UTF-8/UCS conversion is now only based on codetables.xml.
2911 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
2913 --- 2.0.22 2004/08/06
2915 Add support for more "commit changes" in ZOOM (uses Extended Services).
2917 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
2920 Yet another small fix for configure of SSL.
2922 --- 2.0.21 2004/05/14
2924 Fix SSL libs for configure when --with-openssl=DIR is given.
2926 --- 2.0.20 2004/05/10
2928 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
2930 SSL comstack now uses yaz.pem certificate file on server side
2931 by default. Certificate filename can be configured by calling
2932 comstack function cs_set_ssl_certificate_file before cs_bind is used.
2934 Fix bug regarding multiple calls to ZOOM_connection_connect.
2936 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
2938 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
2939 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
2941 ZOOM now allows inspection of X509 peer certificate for verification.
2942 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
2944 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
2945 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
2946 as "modular" but it simplifies things.
2948 Added cs_get_peer_certificate to that returns peer X509 PEM.
2950 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
2951 NULL if SSL is unavailable.
2953 Documentation about MARC decoding tools.
2955 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
2957 --- 2.0.19 2004/03/30
2959 Rename CHANGELOG to NEWS to follow GNU style packing.
2961 Fix bug with missing initialization of member in init_diagnostics.
2962 This bug affects threaded version of GFS server.
2964 --- 2.0.18 2004/03/20
2966 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
2969 Ensure zlib.dll is packed with Windows install.
2971 --- 2.0.17 2004/03/17
2973 Fix encoding of xsd:string to use text instead of CDATA.
2975 Fix endless loop in CQL parser with unbalanced ".
2977 Use a more compact way to store MARC-8 conversion tables.
2979 --- 2.0.16 2004/03/16 Debian only
2981 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
2984 Update CQL parser to use new CQL 1.1 modifiers for booleans and
2989 --- 2.0.15 2004/03/01
2991 Another fix for decoding of XML packed records.
2993 --- 2.0.14 2004/02/25
2995 Fixes for Chunked encoding. White space not ignored after length spec.
2997 Update NS and use default NS for SRW diagnostic elements.
2999 --- 2.0.13 2004/02/23
3001 Implement ZOOM_resultset_cache_reset which resets record cache.
3003 Implement ZOOM_resultset_sort which sorts a result set.
3005 Implement chunked HTTP transfer.
3007 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
3009 --- 2.0.12 2004/02/16
3011 Added member 'schema' to bend_explain_rr structure so that backend
3012 can specify explain record identifier. Defaults to Zeerex 2.0.
3014 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
3016 --- 2.0.11 2004/02/16
3018 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
3021 Added init command for yaz-client which sends "extra" init request.
3023 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
3024 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
3026 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
3028 Make ZOOM error code for "invalid query".
3030 Fixed compilation for SSL which wasn't properly enabled for all platforms.
3032 --- 2.0.10 2004/02/05
3034 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
3037 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
3039 Added option -p <file> to make Generic Frontend Server to write PID file.
3041 Added option -D to put Generic Frontend Server in background on its own.
3043 Make ZOOM C recognize option "password". If unset, "pass" is used
3044 (for backwards compatibility).
3046 Fixed a bug in Generic Frontend Server that could make it crash if a
3047 client sets characterSetNegotation bit, but didn't pass negotiation stuff
3050 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
3051 Must be issued before open, in order to be in effect.
3053 --- 2.0.9-6 2004/01/12 Debian/Windows
3055 Make the SRU server more picky WRT unknown params, etc.
3057 Bug fix: ZOOM scan response didn't return displayTerm - when present.
3059 New YAZ client command, options, that sets Z39.50 options.
3061 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
3062 options from a string of tokens (one token for each option bit).
3064 Update SRW diagnostic code messages.
3066 --- 2.0.9-5 2004/01/07 Debian/Windows
3068 Handle user defined stylesheet for SRW/SRU.
3070 --- 2.0.9-4 2004/01/06 Debian/Windows
3072 Fix bug in decoding of Content-Length.
3074 --- 2.0.9-3 2004/01/06 Debian/Windows
3076 Fix a bug with decoding of XML packed records.
3078 --- 2.0.9-2 2004/01/05 Debian only
3080 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
3082 Fix bug in SRW/SRU diagnostics decoding.
3084 --- 2.0.9 2004/01/05
3086 Fixed bug in Generic Frontend Server which could drop records exceeding
3087 preferred message size. Reported and fixed by Irina Dijour.
3089 Fixed calculation of package size for structured records in Generic
3090 Frontend Server. Reported and fixed by Irina Dijour.
3092 Fixed namespace for SRW/SRU diagnostics.
3094 Fixed SEGV in yaz-client that occured for HTTP connection errors.
3096 --- 2.0.8 2003/12/22
3098 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
3099 this version is incompatible with version 1.0 and older YAZ SRW/SRU
3102 CQL changes to reflect recent changes to the specification:
3103 * Documentation talks about context sets instead of index sets.
3104 * Documentation talks about indexes instead of qualifiers.
3105 * The CQL-to-PQF transformer's configuration file now uses
3106 "index.set.name = <attributes>" instead of the old form
3107 "qualifier.set.name = <attributes>". (Both forms are still
3108 understood but the latter is deprecated.)
3109 * CQL terms with no explicit index specified are now interpreted as
3110 cql.serverChoice instead of srw.serverChoice (which of course
3111 behaves exactly the same.)
3113 --- 2.0.7 2003/12/16
3115 MARC conversion can now generate ISO2709 output in another
3116 character set. yaz-marcdump uses this facility if you invoke it
3119 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
3120 functions from there can be used from C++.
3122 --- 2.0.6 2003/12/04
3124 Frontend server now transfers memory from decoded packages to stream
3127 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
3128 references to show up.
3130 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
3131 the ZOOM Abstract API. The older names for the same options are still
3132 also supported for the benefit of old applications.
3134 ZOOM-C supports "implementationId" and "implementationVersion" options
3135 to go along with "implementationName". These allow the user code to
3136 specify identification strings to be sent to servers.
3137 Add OID for the new ExtLite attribute set.
3139 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
3140 as requested/supplid by Ere Maijala <ere@atp.fi>
3142 For generic frontend server, reverse the order of
3143 "toolkit-supplied / application-supplied" strings sent as implementationId,
3144 Name and Version. Also, remove the spaces around the slash. This brings
3145 the GFS in line with the behaviour of ZOOM-C on the client side.
3147 Add function ZOOM_scanset_display_term.
3149 yaz-client shows scan displayTerm if present.
3151 Utility yaz-iconv is now installed by default along with the man page
3154 Extend configure check for OpenSSL to use pkg-config where available (such
3157 Incorporate patch by Morten Bogeskov which allows a Unix file socket
3158 server to specify uid/gid/mask for socket using the format
3159 unix:[user=uid,][group=gid,][umask=mask,]file=path
3160 If file= is omitted the existing format is assumed, e.g.
3162 in which case the mask is 0666 (rw for everybody).
3164 Major restructure of YAZ source. All source in libyaz is in src directory.
3165 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
3166 util (utility programs such as ASN.1 compiler, yaz-marcdump).
3168 Added man page for utility yaz-marcdump (used to be called marcdump).
3169 yaz-marcdump is installed by 'make install'.
3171 Fixed a memory leak in Generic Frontend Server that occurred when decoding
3172 of incoming package failed.
3174 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
3176 Change prototype of odr_perror: add const to message string.
3178 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
3180 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
3181 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
3182 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
3183 DNS lookup. There should not be any compatibility problems with this
3184 assuming that blocking=1 or 0 is used.
3186 Fix bad reference in UNIX comstack in function cs_addrstr.
3188 Fix for compilation on AIX.
3190 The generic front-end server (server/seshigh.c) now supports returning
3191 Init diagnostics to the client in User-information-field, in
3192 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
3195 --- 2.0.4 2003/09/04
3197 Allow any CQL relation (not just all,any,exact,scr).
3199 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
3200 that features the same UI.
3202 Implemented command update0 in YAZ client which is equivalent to
3203 update but uses old of Ext Update ASN.1.
3205 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
3206 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
3207 Previously no OID was used for this info.
3209 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
3210 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
3211 returns 'malformed search term' otherwise.
3213 SortResponse member resultCount now set to NULL in sort handler of
3216 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
3219 Add three new utility functions for translating OIDs between various
3220 formats -- symbolic name such as "Usmarc", minus-1-terminated int
3221 arrays and dotted strings such as "1.2.840.10003.9.5.1":
3222 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
3223 char *oid_to_dotstring(const int *oid, char *oidbuf);
3224 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
3226 Reverted modifications for ES Update definition for z_IU0Update
3227 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
3228 is back to YAZ 2.0.2.
3230 String value attributes for CCL parser.
3232 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
3233 which their FirstSearch server returns in Init responses, sometimes
3234 carrying useful diagnostic information when Init fails. This has the
3235 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
3236 "z39.50/oclcui.asn", where its definition is somewhat different from
3237 what OCLC document on their web-site, as required to interoperate with
3240 Support for anonymous authentication in yaz-client. Use the command
3243 * Fix the OID of the Index Data-local "admin" Extended Service from
3244 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
3245 the 1000, which indicates a locally-defined OID, was a mistake.
3247 --- 2.0.3 2003/06/20
3249 Fix CCL directive @case handling so that it affects string match for
3250 both CCL keywords and qualifiers.
3252 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
3253 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
3254 Decoder has been updated with ASN.1 changes as listed in
3255 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
3256 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
3257 z_IUUpdate, remains unchanged.
3259 ZOOM_record_get may now return a record in a specific character set.
3260 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
3261 "from" is the character set of record as returned by target. "to" is
3262 the character set to be returned. If omitted, "to" is UTF-8.
3264 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
3266 New ODR utility, odr_getelement, which returns name of element for
3267 which encoding/decoding failed.
3269 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
3270 in cases where a required element was omitted.
3272 Bug fix: some MARC8 sequences were not converted.
3274 New ZOOM option "step" which specifies number of records to be
3275 retrieved in one chunk. Used in conjunction with "start" and "count".
3277 SRW support for yaz-client. Use scheme http: to use it, e.g.
3280 yaz-client no longer does (un)intelligent character set conversions
3281 by default. Can be enabled with charset and marc_charset commands.
3283 xmalloc trace fix for 64-bit systems such as DEC alpha.
3285 Solaris 2.6 compile fix.
3287 New function, cql_strerror() translates SRW error codes, as returned
3288 by cql_transform_error(), into human-readable English strings. Used
3289 in yaz-client diagnostics when appropriate.
3291 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
3292 converts it into a type-1 query which is sent to the server. This
3293 makes CQL available for use with all Z-servers, as opposed to the tiny
3294 minority that can handle CQL queries themselves.
3296 --- 2.0.2 2003/04/28
3298 New Debian package layout similar to the Redhat Package layout.
3300 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
3301 and search result respectively.
3303 --- 2.0.1 2003/04/25
3305 Redhat package is now several packages: libyaz (runtime libraries),
3306 libyaz-devel (development and documentation, and yaz (utility programs).
3307 Package spec file by Morten Bogeskov.
3309 New member 'schema' in struct bend_fetch_rr which the name of requested
3310 schema (SRW/SRU) for record (or NULL if none was given). The fetch
3311 handler MAY set this to reflect the schema of the returned record.
3313 New member 'display_term' in struct scan_entry. GFS now sets member entries
3314 and allocates scan entries to be filled by user scan handler. In previous
3315 version, entries member was allocated by the scan handler. That still works,
3316 but the GFS will ignore member display_term - assuming it was NOT set by
3317 the handler. The fact that the GFS now allocates the entries both allows
3318 for new members and makes a scan handler easier to write.
3320 Fix CQL lex buffer overflow.
3322 SRW/SRU recordPacking. For SRW default recordPacking is string. For
3323 SRU default recordPacking is string.
3325 SRU protocol support for frontend server.
3327 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
3329 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
3331 Added scan for the ZOOM shell (zoomsh).
3335 * String Identifers for Schemas (Amendment 5).
3336 http://lcweb.loc.gov/z3950/agency/amend/am5.html
3337 Old definition for schema
3338 Odr_oid *schema; /* OPT */
3343 Z_InternationalString *uri;
3344 #define Z_Schema_oid 1
3345 #define Z_Schema_uri 2
3348 * resultCount parameter to Sort Response (Amendment 1).
3349 http://lcweb.loc.gov/z3950/agency/amend/am1.html
3351 Support for SRW 1.0 over HTTP. This is an optional feature and
3352 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
3355 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
3356 on the same port. SRW SearchRetrieveRequests are mapped
3357 to bend_init,bend_search,bend_fetch,bend_close.
3359 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
3361 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
3362 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
3364 ZOOM connections are SRW based if schem http is used for hostname
3365 in connect, e.g. z = ZOOM_connection_new("http://myserver");
3366 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
3368 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
3369 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
3370 distance=n, order=true/false, relation=le, prox unit=word. If
3371 n is omitted, distance 1 is used.
3373 Fixed problem with C compiler include path in wrong order.
3375 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
3376 on Solaris. Patch from Ko van der Sloot.
3378 New MARC decode API. All new functions operate on a yaz_marc_t
3379 handle. The most important new functions are: yaz_marc_create,
3380 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
3381 decode and destroy respectively. Decoder can produce formats
3382 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
3383 include/yaz/marcdisp.h.
3385 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
3386 to UTF-8, UCS-32, wchar_t or Latin-1.
3388 * Prototypes for yaz_iconv_-functions moved to separate header
3389 include/yaz/yaz-iconv.h.
3391 Make a few private functions 'static' in unix.c. This prevents
3392 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
3394 For ZOOM connection, the options targetImplementation{Id,Name,Version}
3395 are set when Init Response is received.
3397 New function ZOOM_connection_error_x similar to ZOOM_connection_error
3398 but returns diagnostic set as well.
3400 New function yaz_strerror which is a portable wrapper for
3401 strerror/strerror_r/GetLastMessage.
3403 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
3404 is returned for MARC. If type is "oai", then OAI MARC is returned.
3406 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
3409 --- 1.9.2 2002/11/26
3411 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
3413 Fix bad race conditions on SIGTERM and terminate gracefully in
3416 Move retrieval (data1) module to Zebra since nobody seems to be
3419 Add GRS-1 render for ZOOM using same format as yaz-client.
3421 --- 1.9.1 2002/10/05
3423 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
3425 Fix broken ESpec handling in data1 module.
3427 SGML reader parses comments and makes them part of the data1 tree.
3429 Added several type casts so that YAZ compiles as C++ code.
3431 ZOOM didn't handle PDU encoding failures properly.
3433 Added more Bib-1 diagnostics (approved extensions).
3435 GNU configure: better check for iconv.
3437 More portable use of accept, getpeername. Check for socklen_t. Use
3438 int/size_t if socklen_t is not defined.
3442 PQF parser rejects bad queries - including those with extra
3443 characters in them. PQF parser used to silently ignore that.
3444 Cleaner API for PQF added, which allows you to get detailed
3445 error information for bad queries (see yaz/pquery.h).
3447 Fixed bug in ZOOM_record_get for type "database".
3449 Implemented mini iconv library supporting conversions between
3450 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
3452 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
3454 --- 1.8.9 2002/08/20
3456 Fixed ZOOM C record cache so that preferredRecordSyntax and
3457 elementSetName is used to check for already fetched records.
3459 --- 1.8.8 2002/08/02
3461 Added three members in bend_initrequest structure to facilitate
3462 character set negotiation.
3464 Fixed a bug in frontend server that could cause indefinite
3465 loops under rare conditions.
3467 Revised character set utilities (charneg.h) so that encoding
3468 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
3470 For PQF, directive @term <type> sets term type for Scan/Search.
3471 Here <type> is general, string, numeric, null. The term type
3472 is inherited - just like @attr.
3474 New call odr_set_charset that sets character set conversion for
3475 international-strings on a ODR stream. Prototype is:
3476 int odr_set_charset(ODR o, const char *to, const char *from);
3477 The InternationalString is still represented as C string in YAZ
3478 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
3479 won't). On the protocol level, you can use any encoding.
3481 Support for UNIX sockets in ZOOM.
3483 Solaris recv sometimes returns errno == ENOENT. It is treated as
3484 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
3486 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
3487 both client and server. Code by Morten Bogeskov.
3489 --- 1.8.7 2002/05/22
3491 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
3492 that they can be used directly from Visual Basic. You must recompile
3493 your windows APP if you're using ZOOM.
3495 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
3496 Commands "lang" and "charset" sets language and character set respectively.
3497 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
3498 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
3500 Attributes from multiple CCL fields may be OR'ed rather than merged
3501 using directive "@field or". Fields are still merged by default -
3502 equivalent to "@field merge".
3504 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
3507 Fixed bug in zget for parameter ExtendedServicesResponse.
3511 --- 1.8.6 2002/03/25
3513 Added PQF feature: '@attr type=value' may be written as '@type=value'.
3515 Client displays USR.1:SearchResult-1 (hits per term).
3517 Additional Search Info for search in Generic Frontend Server.
3519 Fixed CCL parsing of "field=s".
3521 WIN32 installer - using the excellent NSIS software from nullsoft.
3523 Fixed CCL parsing of "field = - <number>".
3525 Added function yaz_marc_decode that decodes MARC for line mode
3526 display or XML (similar to that used by JZKit).
3528 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
3529 Z39.50. But ISO/ILL was, however.
3531 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
3532 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
3534 http://lcweb.loc.gov/z3950/agency/amend/am2.html
3535 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
3537 --- 1.8.5 2002/02/03
3539 New YAZ client features: Command completion and new commands:
3540 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
3541 Code provided by Jacob Poulsen.
3543 New call oid_trav, that visits all registered OIDs via callback.
3545 Function ZOOM_record_get now returns const char pointer rather than
3546 void pointer. It saves a lot of type casts.
3548 For YAZ client, command "auth" now allows you to set authentication
3549 in IdPass style. It is enabled when three tokens are given - order
3550 is user, group and password.
3552 Fix memory leaks in MARC record handling for ZOOM.
3554 New option for YAZ client, -k <kilobytes> that sets
3555 maximum record size. Similar to -k option for generic frontend
3556 server and yaz-ztest.
3558 More fixes for scan. Non-zero stepSize handled. OID's fixes.
3560 Prefix query parser reports "fail" when bad attribute set is given.
3562 Fix in MARC decoder. Proximity logging. Fix for attribute set
3563 in scan handler for server. Patches by Shigeru Ishida.
3565 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
3568 Configure option --with-openssl=<dir> now works when a directory is
3569 specified. Patch provided by Morten Bogeskov.
3571 New option for YAZ client, -u <auth>, that sets authentication.
3573 ZOOM fix: error information was sometimes "missing", since error
3574 was cleared/reset too when it shouldn't.
3576 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
3578 --- 1.8.4 2002/01/04
3580 Scan for ZOOM API. New object ZOOM_scanset. New functions
3581 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
3582 ZOOM_scanset_destroy.
3584 New ZOOM function, ZOOM_connection_last_event, that returns type
3585 of last event (such as "receive data", "send data", "apdu received",
3588 New ZOOM option, schema, that specifies schema for retrieval.
3590 New CCL feature. Qualifiers can be aliases for one or more
3591 other qualifiers (if more than one is given, OR is used).
3593 ZOOM uses named result sets if target supports it.
3595 Two new YAZ client commands: . (dot, which sources a script of YAZ
3596 client commands), and ! (to execute shell command.). Implemented
3599 Working on Debian packages.
3601 --- 1.8.3 2001/11/19
3603 YAZ client enables named result sets only if target supports it.
3605 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
3607 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
3608 with key="host" to get same result.
3610 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
3611 Function Z3950_resultset_record(s) returns references to records
3612 "owned" by resultset. To become owner use Z3950_record_clone.
3614 Function z_ext_record handles Extended Services. Thanks to
3617 --- 1.8.2 2001/11/12
3619 CCL Parser fix: ignore token comma when dealing with and-lists.
3621 Documentation updates for COMSTACK.
3623 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
3624 Changed prototype Z3950_records. For some functions, int parameters
3625 were changed to size_t.
3627 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
3630 New MARC decode/display function, marc_display_exl, which properly rejects
3631 non-ISO2709 records. YAZ client uses it.
3633 --- 1.8.1 2001/10/29
3635 Fix bug: local attribute set wasn't set correctly in PQF strings.
3639 * Old Z39.50 codecs no longer supported.
3641 Added ZOOM C binding. See http://zoom.z3950.org/
3643 Renamed states for COMSTACKs to avoid confusion with events.
3645 Implemented cs_look and proper cs_rcvconnect.
3647 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
3649 Configure detects POSIX threads on OpenBSD.
3651 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
3652 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
3654 When error is returned from present handler, non-surrogate diagnostic
3655 is returned in present response (and fetch handler is no longer called).
3657 * Minor adjustments to pquery parser (PQF). Token characters may be
3658 escaped by using backslash (C-style).
3660 PQF parser allows string attribute values to be specified. For @attr,
3661 non-numeric characters after the equal-sign are treated as strings
3662 (e.g. @attr 9=title).
3664 CCL trunction character may be defined (@truncation in file)
3666 * function zget_ExtendedServicesRequest sets waitAction to
3667 waitIfPossible (was wait).
3669 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
3672 CCL operator names may be set in field definition files (CCL_bibset).
3673 See ccl/bib1 for an example.
3675 Fixes in ASN.1 compiler for C++ compatibility.
3677 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
3678 and "op_or" to avoid conflict with C++.
3680 Fixed problem with GNU readline detection on Redhat 7.0.
3682 Added step-size for Scan backend handler.
3684 Fixed bug that made the frontend server crash when no attribute
3685 set was specified for scan.
3687 Front-end server automatically switches to original working directory
3688 when installed as an NT service. Previously -w had to be specified to
3691 Added extended attributes for retrieval module (data1), so that data1
3692 records carry d1_readXML/SGML attributes. d1_read also supports
3693 null-data rules ( <tag/>)
3695 On UNIX when POSIX threads are available, a separate library libyazthread
3696 is created. Programmers should link with that library and the yaz library
3697 when using threads. The reason for the split was that some applications
3698 on Linux, such as Apache, doesn't work well when using shared objects that
3701 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
3702 (or any frontend server) in SSL mode by specifying ssl: followed by
3703 address. Only tested on UNIX.
3705 Added feature for CCL module. Virtual structure s=al or s=ol generates
3706 and-list and or-list respectively instead of phrase search.
3710 * Added prefix "yaz_" for the functions log_init.., log_file.. and
3711 log_mask_str. This was done to avoid name conflicts with other libraries
3712 (such as other PHP extensions).
3714 Added raw OID member for preferred record syntax (request_format_raw)
3715 and returned record syntax (output_format_raw) for backend fetch method.
3717 Config file yaz-config now accepts options so that it returns specific
3718 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
3720 Shared library support for UNIX using GNU libtool.
3722 * Modified backend interface. Request/Response struct's replaced by
3723 one read/write C struct. For example bend_fetchrequest and
3724 bend_fetchresult have been replaced by single bend_fetch_rr struct.
3725 Every handler - even search has to be registered in bend_init
3726 handler. This means that the YAZ library no longer refers to
3727 external functions and it makes it possible to make the whole
3728 thing a single DLL/SO.
3730 Added Segment handler for backend server.
3732 Added Zmbol/Zebra administrative functions to YAZ client.
3734 Threaded frontend server on UNIX (when POSIX Threads are available).
3735 Starting the server with option -T enables multi-threading.
3739 Added configure option --enable-comp/disable-comp to control use
3740 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
3741 located in sub directory asn.
3743 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
3744 in ${exec_prefix}/bin along with the other programs yaz-client and
3747 GNU automake used to maintain makefiles.
3749 Added several OID's.
3751 Changed retrieval module so that we can load records with no abstract
3752 syntax defined. Tagpaths in these records are fully composed of string
3755 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
3759 On UNIX, the generated makefile now supports a proper 'make install'.
3760 The prefix can be set via GNU configure to set the install location
3761 (default is /usr/local).
3763 * YAZ programs client and ztest were renamed to yaz-client and
3764 yaz-ztest to avoid conflicts when users install YAZ in "standard"
3765 locations, such as /usr/bin,/usr/local/bin,etc.
3767 * YAZ Header files were moved from include to include/yaz. YAZ Header
3768 files are referred to as include <yaz/log.h> rather than <log.h>.
3769 The YAZ include path (-I ..) is therefore the same as before. Programmers
3770 should update their #include statements or use -Ipath/include/yaz
3771 instead. The main motivation for doing this change is that YAZ header files
3772 can be installed in "standard" locations /usr/include,/usr/local/include
3773 without introducing conflicts, since ALL YAZ header files are stored
3774 in subdirectory yaz (under /usr/include for example).
3776 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
3777 rather than project/workspace files. We switched because project files
3778 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
3781 Changed name of logging function, logf, to yaz_log, to prevent name
3782 clash with some math-log functions. The YAZ header log.h defines logf
3783 to yaz_log (#define) so there should be no incompatibilities by this
3786 Added bend_start/bend_stop handlers for server. These handler are
3787 called on start/stop of server. For windows they are called whenever
3788 a service is started/stopped.
3790 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
3791 a fairly small ASN.1 compiler written in Tcl. The compiler is located
3792 in util/yc.tcl. The auto-generated C code structures are, in a few
3793 cases, incompatible with the old decoders. There are differences in the
3794 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
3795 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
3796 The preprocessor variable ASN_COMPILED is defined when the compiled
3797 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
3798 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
3799 wish to use the old encoders/decoders you can specify --disable-yc
3802 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
3803 version so that it supports both new - and old version of DB Update
3805 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
3806 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
3807 change. The name parameter can be set to 0 in which no name is specified
3808 for the construction. The macros odr_implicit and odr_explicit sets name
3809 parameter to zero for the construction involved. New macros
3810 odr_implicit_tag and odr_explicit_tag are similar to the others,
3811 except that a name parameter is added. For programmers' that don't use
3812 ODR they probably only need to change the call to z_APDU and z_External.
3814 Added access control facility by interfacing the TCP wrapper library.
3815 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
3816 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
3817 name of the daemon and enables the access control as specified in
3818 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
3820 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
3821 den Dool <H.M.vdnDool@kub.nl>.
3823 Added reference ID parameter to most functions in server API - refer
3824 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
3826 Changed name of ccl library to libccl.a (was ccl.a).
3828 Fixed bug in decoder for Explain (Category TargetInfo).
3830 Added support for GNU readline in client. Thanks to Jacob Poulsen
3831 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
3833 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
3834 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
3835 IMPLEMENTATION! This change was made to the development version before
3836 the ZIG decided to retract the amendment. If any users MUST be
3837 compatible with the original Update definition, PLEASE CONTACT US, and
3838 we will include a separate definition corresponding to the old Update
3839 ES. Note that because of the change to the ASN.1 of the
3840 TaskPackageRecordStructure we cannot define a single structure that
3841 will support both versions.
3843 * Added const modifier to buffer parameter for some ODR/BER encoding
3844 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
3845 completeWAIS, odr_dumpBER.
3847 Fixed bug in client.c which caused a crash when a scanResponse didn't
3848 contain positionOfTerm.
3850 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
3851 * will cause an error in a client if a non-YAZ target sends both a
3852 * list of Scan entries and non-surrogate diagnostics.
3854 Retrieval module enhancements. Tag sets may be typed in the reference
3855 to it. From the .abs-file the "tagset" directive takes a third optional
3856 integer type for the tag set referenced. From a .tag-file the "include"
3857 directive takes a third optional type as well. The old "type" directive
3858 in the tag set itself is still recognized but acts as the default type
3861 Backend interface change. Individual Scan terms returned from bend_scan
3862 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
3863 in include/backend.h.
3865 Retrieval module enhancements. Multiple tag sets and attribute sets may
3866 be specified in abstract syntax specs. Revised the error/warning for
3867 logging messages reported by the retrieval module when reading the
3870 Object Identifier system (oid_..) changed. The API is backwards
3871 compatible but the oid-routines now allocates new OID's when needed.
3872 Raw OID's may be specified in oid_getvalbyname.
3874 YAZ now uses GNU configure to generate Makefile(s).
3876 * Minor changes in some of the member names of DeleteResultSetRequest and
3877 DeleteResultSetResponse. See include/proto.h.
3879 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
3880 and added member 'languages' in TargetInfo (which was missing).
3882 Changed the way attribute sets are handled in the retrieval
3883 module. These are now cached, just like the abstract syntaxes
3886 Changed YAZ so that it links with compiled ASN.1.
3888 Added Explain-schema definitions and mapping routines. The following
3889 Explain categories have been implemented: AttributeDetails,
3890 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
3892 Fixed minor bug in Windows version of Server Library.
3894 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
3896 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
3898 Added EXTERNAL: UNIverse Resource Report (non-standard).
3900 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
3901 ENUMERATED and SET OF.
3903 * Added 'const' to some of the char pointer arguments for the
3904 functions, data1_read_node, data1_getelementbytagname,
3905 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
3908 Fixed bug in data1_insert_taggeddata - the last_child member of
3909 parent wasn't initialised.
3911 * Changed data1_read_record and data1_read_node so that the supplied
3912 "SGML"-buffer is read-only. In particular the resulting data1 - tree
3913 doesn't refer to any parts of the "SGML"-buffer.
3915 Fixed bug in server library (Windows version of statserv_remove).
3917 * Changed code so that it compiles as C++. The type definition
3918 of Odr_fun which is a member of Odr_arm was changed. The result is,
3919 that an explicit typecast is needed for the fun pointer when
3920 using Odr_arm - as in:
3921 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
3923 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
3925 Implemented the new structured date and time definition as approved
3926 by the ZIG. Added schemaId element to the specificTag in Espec-1
3927 (also approved at the last ZIG). Thanks to RVDM.
3929 Added some Object identifiers (RVDM).
3931 Changed the Update Extended Service (RVDM).
3933 Added command "refid" to client which specifies referenceId for
3934 the following requests.
3936 Implemented extended service handling for server. See ztest.c
3937 for an example as well as backend.h. New handlers are registerd
3938 in the Init handler.
3940 * Changed interface for sort in server.
3942 Added new members to statserv_options_block. It allows a server
3943 to read options from another source than just the command line. Thanks
3944 to Charles Woodfield.
3946 * Changed definition of Z_Triple in file prt-grs.h - member boolean
3947 renamed to zboolean. Some C++ compilers complained about the name.
3949 Minor changes to gils.abs. Added index 's' (sort) on title
3950 and date/time-last-modified.
3952 --- 1.4pl2 1998/1/30
3954 Fixed bug in server library regarding inetd mode (-i). This bug
3955 was introduced by release 1.4.
3957 --- 1.4pl1 1998/1/29
3959 Added sort facility in client and backend server interface.
3961 Fixed problem with dependencies in Makefile(s).
3963 Fixed bugs for encoders/decoders of extended services and
3966 Implemented sub-tree feature for schemas. Sub-trees are
3967 referenced in *.abs-files. See explain.abs for an example
3968 of the use of this feature.
3970 Modified bib1.att; local attributes for ANY didn't include
3971 ANY itself (only affects use of the retrieval module).
3973 Fixed bug in plain SGML reader in function data1_read_node:
3974 tags with prefix "var" was incorrectly interpreted as variants.
3976 Added feature "sub-schemas" to enable references to - and definitions
3977 of - group of elements.
3979 * Removed member parent from type data1_element (in data1.h).
3981 Implemented function odr_nullval() that returns the value of
3984 * Removed member num_children from data1_node (in data1.h).
3986 Made NT service interface part of the server library. The
3987 function statserv_main uses the NT service when required and
3988 calls the statserv_start / statserv_close routines.
3990 Routine zget_SearchRequest and zget_PresentRequest fills
3991 resultSetName/Id member with "default" instead of "Default".
3993 Fixed memory leak in server. Request queue member wasn't freed.
3995 Fixed nmem_exit so that memory is freed.
3999 Revised the CCL parser utility to be thread safe.
4001 Added function, oid_ent_to_oid, to replace the function
4002 oid_getoidbyent, which is not thread safe.
4004 * Added nmem_init and nmem_exit to initialize and release
4005 NMEM resources. Function nmem_init should be called once in the
4006 initial thread before NMEM/ODR is used. statserv.c and client.c
4007 have been changed accordingly. The change was necessary to make
4008 NMEM thread safe. The NMEM memory pool is shared amongst threads
4009 in a process. Unix-based applications will still work fine without
4012 Added NT Services interface for the the Z39.50 (statserv) Server.
4013 Refer to the ztest.c source on the usage.
4015 Windows 95/NT port using MSVC5.0. Project files are included in the
4018 * Defined new 'global' handle for the retrieval (data1) system. The
4019 new handled, data1_handle, describes the state of the data1 system.
4020 This handle is passed as first argument to virtually all
4021 data1 related routines. The functions data1_create and data1_destroy
4022 creates and destroys a data1 handle respectively.
4024 Added ODR encode stream member to all backend request structures
4025 init, search, scan etc. This stream should be used to allocate all
4026 memory used for the response when thread safe operation is needed.
4028 Changed the comstack utility, cs_addstr, to be thread safe. The
4029 returned hostname string returned by the function is now part the
4032 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
4033 function. The cs_straddr takes a COMSTACK handle as argument, so this
4034 function must be used after cs_create and before bind/connect.
4035 This function is thread safe.
4037 Moved test server to 'ztest' directory - generic server code still
4038 in 'server' directory.
4040 Made prefix query (pquery.c) utility thread safe.
4042 Added new function modifier YAZ_EXPORT to 'export' public DLL
4043 functions when using windows (see include/yconfig.h).
4045 Added definitions to the OID database (util/oid.c) (RVDM).
4047 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
4049 Added call to ccl_rpn_delete in client program.
4051 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
4052 release of RPN structure.
4054 Added support for C++, headers uses extern "C" for public definitions.
4055 With input from RVDM.
4057 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
4058 Thanks to Ronald van der Meer (RVDM).
4060 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
4062 Added support for private extensions to the OID database
4063 (oid_setprivateoids()). Thanks to RVDM.
4065 Added optional, physical ANY (key replication)
4067 Fixed null-reference problem in GRS-1 output filter.
4069 Proximity operator added to Prefix Query Format (PQF).
4071 In test client command "base" accepts multiple databases.
4073 Fixed bug in cs_close stack that caused trouble with WINSOCK.
4077 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4079 Smallish bug-fixes in the new encoders/decoders (explain).
4081 Bug fixed in DeleteRequest.
4083 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
4085 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
4087 Added SOIF syntax (using private OID for now) to retrieval module and client.
4089 Added Update extended service.
4091 Added SearchResult-1 additional info structure.
4093 Added optional CCL (ISO8777) interpreter as separate module. Available
4096 --- 1.2 1996/6/10 (1st anniversary release)
4098 Added Summary record syntax. Lightly tested.
4100 Added OPAC record syntax. Untested.
4102 Added ResourceReport service encoders/decoders. Untested.
4104 Fixed bug in z_Unit - wrong tagging on unitSystem.
4106 Fixed bug in the DiagRecs decoder.
4108 Added options for max PDU size and session timeout to frontend-server.
4110 Added documentation of query-language parsers and other supporting utilities.
4112 [frontend-server] Added Attribute set to the bend_scanrequest API.
4114 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
4115 surrogate diagnostics were generated.
4117 [retrieval] Allow multiple local values for attribute.
4119 [retrieval] Allow multiple attributes per element in .abs files. index type.
4121 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
4123 --- 1.1pl2 1996/4/10
4125 Minor changes, mostly specific to Zebra's requirements (retrieval)
4129 Repaired bug in frontend server when running multiple listening
4130 endpoints in dynamic mode.
4132 z_External() now won't break if a known, ASN.1 value comes encapsulated
4133 in an octet-string. The value will pass through unmodified in an Odr_oct.
4135 Added a bit of code to the demo client to decode & display
4136 ASN.1-structured records represented in the octet-aligned branch of
4137 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
4139 Added z_ext_getentbyref() to the ASN module. Doc updated.
4141 * Completed the SCAN definition in the ASN module. This may break SCAN
4142 code based on older YAZ-versions at compile-time. The fix is easy -
4145 * Added 'displayTerm' and OtherInformation to the TermInfo structure
4146 under the SCAN definition. Remember to initialize this, server-people.
4148 Comstack should now support the WAIS protocol in TCP/IP mode. Note
4149 that this does not extend to ODR and ASN.
4151 Comstack allows insertion of established socket (primarily for
4152 inetd-operation of servers). Doc updated.
4154 Front-end server can now start from the inetd in TCP mode. Doc
4157 --- 1.0pl4 1996/1/24
4161 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
4162 the rank and record number.
4164 Adjustments to the frontend server.
4166 Fixed diagnostic BER dumper. It ignored the file argument.
4170 Various changes to retrieval module.
4172 Changed the union discriminators of the protocol files from enums to
4173 ints paired with #defines.
4175 *Changed oident.class to oident.oclass to avoid a reserved word in C++
4178 *Changed operator in the RPN structure to 'roperator', again to avoid a
4181 Fixed problems in Explain decoders/encoders.
4183 --- 1.0pl2 1995/12/6
4185 Memory bug in log module fixed.
4187 --- 1.0pl1 1995/12/5
4189 Occasional malloc() of 0 bytes fixed in d1_espec.c.
4191 Bug in Explain DatabaseInfo module fixed.
4193 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
4197 The shift to v1.0 signals that we now consider the *core* functionality
4198 of YAZ reasonably stable (the core being more or less equivalent to
4199 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
4200 tested (Explain not at all - though that will happen soonish).
4202 Minor changes to code to support Windows port.
4204 Various minor changes after we're getting to use GRS-1 & co. more.
4206 Added Espec-1 format.
4208 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
4209 of the protocol and it cannot be selected when encoding (maps into 'string'
4210 when decoding). Needed to talk to some servers.
4212 Demo client can request simple element set names.
4214 Added Diagnostic Format encoders/decoders.
4216 Added simple Close handling to frontend server (no hooks for resource
4217 reporting yet), and demonstration client.
4219 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
4221 --- 1.0b3 1995/08/24
4223 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
4224 handled incorrectly when records were requested in the searchResponse. This
4225 will only affect you if you use the frontend-server.
4227 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
4228 Test-client will ask for and print GRS1. Ztest will return dummy records
4231 Added Explain encoders/decoders to the service-level API. Untested.
4233 Added Extended Services: Item Order encoders and decoders to the Service-
4234 level API. Untested. We could use a recent copy of the pertinent bits
4235 of the ILL protocol to add those bits.
4237 Added diagnostic format 1 encoders/decoders to the service-level API.
4240 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
4241 odr_cons.c, which causes a more correct output.
4243 Fixed handling of searchRequest in frontend server. NextResultSetPosition
4244 was always set to 0 when no records were requested in the searchRequest.
4246 * Added better external-handling. This shouldn't harm old code that
4247 *encodes* externals. It can break code that looks for a
4248 'single-ASN1-type' representation, since those types that are known
4249 are now decoded immediately. Look at the SUTRS sample code in
4250 seshigh.c and client.c. Documentation updated.
4252 Handling of structured records in bend_fetchresponse. Length -1 marks
4253 structured record, type is deduced from format field.
4255 --- 1.0b2 1995/06/27
4256 Fairly quick maintenance release to add SUTRS support.
4258 Fixed handling of SUTRS records in the demonstration client.
4260 * Added format field to the bend_fetchrequest and bend_fetchresponce
4261 structures of the backend API (frontend server). When the record is
4262 returned, the value of the format field is mapped to an OID. The
4263 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
4264 of the record. The special value VAL_NONE in the bend_request means
4265 that no specific format was requested by the client. Documentation
4266 updated accordingly. Test server (ztest) will return a fixed dummy
4267 SUTRS record if your client requests SUTRS.
4269 Documentation updated accordingly.
4271 You can now set external libraries and RANLIB support in the top-level
4275 First public release.
